目前还有很多公司基于HDP来构建自己的大数据平台，随着Apache Kyuubi的持续热度，如何基于原有的HDP产品来集成Apache Kyuubi，很多人都迫切的需求。集成Apache Kyuubi到HDP中，主要涉及Ambari的二次开发。本文详细叙述了集成Apache Kyuubi的实践过程。
1、集成版本信息
| 服务 | 版本 |
| 九尾 | 1.4.1-孵化 |
| 安巴里 | 2.7.3 |
| 高清图 | 3.1.0 |
| 操作系统 | CentOS 7.4.1708 |
背景：基于HDP 3.1.0版本，我司完成了Apache版本的所有组件替换，然后集成了Apache Kyuubi。
集成Apache的主要组件版本信息如下
| 服务 | 版本 |
| 高清文件系统 | 3.3.0 |
| 纱 | 3.3.0 |
| MapReduce2 | 3.3.0 |
| 蜂巢 | 3.1.2 |
| 火花 | 3.1.1 |
2、集成步骤
自定义组件添加分为两大部分，一部分是需要将组件的可文件打包成RPM，另一部分是在Ambari 中添加组件的配置信息，启动脚本等。
2.1 制作RPM包
使用Ambari 安装或集成大数据组件时，需要将组件格式制作成 rpm 格式。
2.1.1 下载并解压Apache Kyuubi
下载地址：https://kyuubi.apache.org/releases.html
在本次集成中我们选择的是1.4.1-incubating版本。
执行tar zxf apache-kyuubi-1.4.1-incubating-bin.tgz，Kyuubi安装包结构简介

2.1.2 创建RPM包制作环境
安装 rpm-build 包
yum install rpm-build安装 rpmdevtools
yum install rpmdevtools创建工作空间
rpmdev-setuptree安装工作空间简介
2.1.3 制作RPM包
2.1.3.1 编辑Spec文件
制作rpm包需要用spec格式的文件。根据Kyuubi解压后的目录结构，需要自行编辑spec文件以包含所有需要的目录及文件。部分截图概要
%descriptionkyuubi%files%dir %attr(0755, root, root) "/usr/hdp/3.1.0.0-78/kyuubi"%attr(0644, root, root) "/usr/hdp/3.1.0.0-78/kyuubi/DISCLAIMER"%attr(0644, root, root) "/usr/hdp/3.1.0.0-78/kyuubi/LICENSE"%attr(0644, root, root) "/usr/hdp/3.1.0.0-78/kyuubi/NOTICE"%attr(0644, root, root) "/usr/hdp/3.1.0.0-78/kyuubi/RELEASE"%dir %attr(0777, root, root) "/usr/hdp/3.1.0.0-78/kyuubi/beeline-jars"%dir %attr(0777, root, root) "/usr/hdp/3.1.0.0-78/kyuubi/logs"%dir %attr(0777, root, root) "/usr/hdp/3.1.0.0-78/kyuubi/pid"%dir %attr(0777, root, root) "/usr/hdp/3.1.0.0-78/kyuubi/work"%changelog
2.1.3.2 更换文件
创建目录
cd /root/rpmbuild/BUILDROOTmkdir -p /root/rpmbuild/BUILDROOT/kyuubi_3_1_0_0_78-2.3.2.3.1.0.0-78.x86_64/usr/hdp/3.1.0.0-78/kyuubi
转到apache-kyuubi-1.4.1-incubating-bin.tgz解压后目录
cp -r * /root/rpmbuild/BUILDROOT/kyuubi_3_1_0_0_78-2.3.2.3.1.0.0-78.x86_64/usr/hdp/3.1.0.0-78/kyuubi将kyuubi.spec文件放到/root/rpmbuild/SPECS文件夹中
cp kyuubi.spec /root/rpmbuild/SPECS/2.1.3.3 执行打包。
cd /root/rpmbuild/SPECSrpmbuild -ba kyuubi.spec
查看 rpm 包
打包好的rpm包在/root/rpmbuild/RPMS虚拟机
2.1.4更新YUM源
将上步骤中生成rpm的目标yum源中对应目录，保持完成后执行更新操作
createrepo --update ./2.2 Ambari集成Apache Kyuubi
2.2.1 公民服务目录结构
在Ambari中添加自定义服务，需要配置文件以Spark详细说明
配置
该目录下存放的是spark的属性配置文件，对应Ambari页面的属性配置页面，可以设置默认值，类型，描述等信息。
包/脚本
该目录下存放服务操作相关的脚本，如服务启动，服务停止，服务检查等。
包/模板
该目录可存放，存放的是组件属性的配置信息，和配置目录下的配置对应，这个关系是如果我们在Ambari页面修改了属性信息，则修改信息会自动填充该目录下的文件的属性，所以，这个目录下的属性是最新的，并且是服务要调用
包裹/警报
该程序存放告急配置，例如程序断网、运行时告急
快速链接
该目录下存放的是快速链接配置，Ambari页面通过该配置可以跳转到我们想要跳转的页面。
指标.json
用来配置指标相关配置
kerberos.json
用来配置kerberos认证
元信息文件
这个文件很重要，主要是配置服务名称、服务类型、服务操作脚本、服务组件、指标以及快速链接等信息。
2.2.2 添加Kyuubi组件
在司的应用场景中，主要是用Kyuubi来替换Spark Thrift Server，依赖于Spark服务中集成Kyuubi组件。实现如下图所示的效果
2.2.2.1 编辑metainfo.xml
在ambari-server/src/main/resources/stacks/HDP/3.0/services/SPARK目录中首先编辑metainfo.xml，为spark服务添加Kyuubi组件
<component><name>KYUUBI_SEVER</name><displayName>KYUUBI SEVER</displayName><category>SLAVE</category><cardinality>0+</cardinality><versionAdvertised>true</versionAdvertised><dependencies><dependency><name>HDFS/HDFS_CLIENT</name><scope>host</scope><auto-deploy><enabled>true</enabled></auto-deploy></dependency><dependency><name>MAPREDUCE2/MAPREDUCE2_CLIENT</name><scope>host</scope><auto-deploy><enabled>true</enabled></auto-deploy></dependency><dependency><name>YARN/YARN_CLIENT</name><scope>host</scope><auto-deploy><enabled>true</enabled></auto-deploy></dependency><dependency><name>SPARK/SPARK_CLIENT</name><scope>host</scope><auto-deploy><enabled>true</enabled></auto-deploy></dependency><dependency><name>HIVE/HIVE_METASTORE</name><scope>cluster</scope><auto-deploy><enabled>true</enabled></auto-deploy></dependency></dependencies><commandScript><script>scripts/kyuubi_server.py</script><scriptType>PYTHON</scriptType><timeout>600</timeout></commandScript><logs><log><logId>kyuubi_server</logId><primary>true</primary></log></logs></component>
其中kyuubi_server.py定义了安装、配置、启动、停止、获取服务状态等功能。
<configuration-dependencies><config-type>core-site</config-type><config-type>spark-defaults</config-type><config-type>spark-env</config-type><config-type>spark-log4j-properties</config-type><config-type>spark-metrics-properties</config-type><config-type>spark-thrift-sparkconf</config-type><config-type>spark-hive-site-override</config-type><config-type>spark-thrift-fairscheduler</config-type><config-type>kyuubi-defaults</config-type><config-type>kyuubi-env</config-type><config-type>kyuubi-log4j-properties</config-type><config-type>ranger-spark-audit</config-type><config-type>ranger-spark-security</config-type></configuration-dependencies>
在< configuration-dependencies ></ configuration-dependencies >标签内添加kyuubi相关配置项，包括kyuubi-defaults、kyuubi-env、kyuubi-log4j-properties、ranger-spark-audit、ranger-spark-security。
<osSpecific><osFamily>redhat7,amazonlinux2,redhat6,suse11,suse12</osFamily><packages><package><name>spark2_${stack_version}</name></package><package><name>spark2_${stack_version}-python</name></package><package><name>kyuubi_${stack_version}</name></package></packages></osSpecific>
在< package > </ package >标签内添加kyuubi rpm包名称信息
2.2.2.2 编辑kyuubi_server.py文件
#!/usr/bin/env pythonimport osfrom resource_management import *class KyuubiServer(Script):def install(self, env):self.install_packages(env)def configure(self, env, upgrade_type=None, config_dir=None):import kyuubi_paramsenv.set_params(kyuubi_params)Directory([kyuubi_params.kyuubi_log_dir, kyuubi_params.kyuubi_pid_dir, kyuubi_params.kyuubi_metrics_dir, kyuubi_params.kyuubi_operation_log_dir],owner=kyuubi_params.kyuubi_user,group=kyuubi_params.kyuubi_group,mode=0775,create_parents = True)kyuubi_defaults = dict(kyuubi_params.config['configurations']['kyuubi-defaults'])PropertiesFile(format("{kyuubi_conf_dir}/kyuubi-defaults.conf"),properties = kyuubi_defaults,key_value_delimiter = " ",owner=kyuubi_params.kyuubi_user,group=kyuubi_params.kyuubi_group,mode=0644)# create kyuubi-env.sh in kyuubi install dirFile(os.path.join(kyuubi_params.kyuubi_conf_dir, 'kyuubi-env.sh'),owner=kyuubi_params.kyuubi_user,group=kyuubi_params.kyuubi_group,content=InlineTemplate(kyuubi_params.kyuubi_env_sh),mode=0644,)#create log4j.properties kyuubi install dirFile(os.path.join(kyuubi_params.kyuubi_conf_dir, 'log4j.properties'),owner=kyuubi_params.kyuubi_user,group=kyuubi_params.kyuubi_group,content=kyuubi_params.kyuubi_log4j_properties,mode=0644,)def start(self, env, upgrade_type=None):import kyuubi_paramsenv.set_params(kyuubi_params)self.configure(env)Execute(kyuubi_params.kyuubi_start_cmd,user=kyuubi_params.kyuubi_user,environment={'JAVA_HOME': kyuubi_params.java_home})def stop(self, env, upgrade_type=None):import kyuubi_paramsenv.set_params(kyuubi_params)self.configure(env)Execute(kyuubi_params.kyuubi_stop_cmd,user=kyuubi_params.kyuubi_user,environment={'JAVA_HOME': kyuubi_params.java_home})def status(self, env):import kyuubi_paramsenv.set_params(kyuubi_params)check_process_status(kyuubi_params.kyuubi_pid_file)def get_user(self):import kyuubi_paramsreturn kyuubi_params.kyuubi_userdef get_pid_files(self):import kyuubi_paramsreturn [kyuubi_params.kyuubi_pid_file]if __name__ == "__main__":KyuubiServer().execute()
kyuubi_server.py定义了安装、配置、启动、停止Kyuubi服务的逻辑。
kyuubi_params配置变量以及需要的相关参数，由于篇幅原因这里不推荐使用。
2.2.2.3 编辑kyuubi_default.xml文件
<?xml version="1.0" encoding="UTF-8"?><configuration supports_final="true"><property><name>kyuubi.ha.zookeeper.quorum</name><value>{{cluster_zookeeper_quorum}}</value><description>The connection string for the zookeeper ensemble</description><on-ambari-upgrade add="true"/></property><property><name>kyuubi.frontend.thrift.binary.bind.port</name><value>10009</value><description>Port of the machine on which to run the thrift frontend service via binary protocol.</description><on-ambari-upgrade add="true"/></property><property><name>kyuubi.ha.zookeeper.session.timeout</name><value>600000</value><description>The timeout(ms) of a connected session to be idled</description><on-ambari-upgrade add="true"/></property><property><name>kyuubi.session.engine.initialize.timeout</name><value>300000</value><description>Timeout for starting the background engine, e.g. SparkSQLEngine.</description><on-ambari-upgrade add="true"/></property><property><name>kyuubi.authentication</name><value>{{kyuubi_authentication}}</value><description>Client authentication types</description><on-ambari-upgrade add="true"/></property><property><name>spark.master</name><value>yarn</value><description>The deploying mode of spark application.</description><on-ambari-upgrade add="true"/></property><property><name>spark.submit.deployMode</name><value>cluster</value><description>spark submit deploy mode</description><on-ambari-upgrade add="true"/></property><property><name>spark.yarn.queue</name><value>default</value><description>The name of the YARN queue to which the application is submitted.</description><depends-on><property><type>capacity-scheduler</type><name>yarn.scheduler.capacity.root.queues</name></property></depends-on><on-ambari-upgrade add="false"/></property><property><name>spark.yarn.driver.memory</name><value>4g</value><description>spark yarn driver momory</description><on-ambari-upgrade add="false"/></property><property><name>spark.executor.memory</name><value>4g</value><description>spark.executor.memory</description><on-ambari-upgrade add="false"/></property><property><name>spark.sql.extensions</name><value>org.apache.submarine.spark.security.api.RangerSparkSQLExtension</value><description>spark sql ranger extension</description><on-ambari-upgrade add="false"/></property></configuration>
其中kyuubi.ha.zookeeper.quorum属性配置的值值为{{cluster_zookeeper_quorum}}，会在kyuubi安装中自动替换为当前zk集群的信息。
kyuubi.authentication属性配置的值值为{{kyuubi_authentication}}，在kyuubi安装中判断当前集群是否开启kerberos认证，来设置true或者false。
2.2.2.4 编辑kyuubi_env.xml文件
<?xml version="1.0"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?><configuration supports_adding_forbidden="true"><property><name>kyuubi_user</name><display-name>Kyuubi User</display-name><value>spark</value><property-type>USER</property-type><value-attributes><type>user</type><overridable>false</overridable><user-groups><property><type>cluster-env</type><name>user_group</name></property><property><type>kyuubi-env</type><name>kyuubi_group</name></property></user-groups></value-attributes><on-ambari-upgrade add="true"/></property><property><name>kyuubi_group</name><display-name>Kyuubi Group</display-name><value>spark</value><property-type>GROUP</property-type><description>kyuubi group</description><value-attributes><type>user</type></value-attributes><on-ambari-upgrade add="true"/></property><property><name>kyuubi_log_dir</name><display-name>Kyuubi Log directory</display-name><value>/var/log/kyuubi</value><description>Kyuubi Log Dir</description><value-attributes><type>directory</type></value-attributes><on-ambari-upgrade add="true"/></property><property><name>kyuubi_pid_dir</name><display-name>Kyuubi PID directory</display-name><value>/var/run/kyuubi</value><value-attributes><type>directory</type></value-attributes><on-ambari-upgrade add="true"/></property><!-- kyuubi-env.sh --><property><name>content</name><description>This is the jinja template for kyuubi-env.sh file</description><value>#!/usr/bin/env bashexport JAVA_HOME={{java_home}}export HADOOP_CONF_DIR=/etc/hadoop/confexport SPARK_HOME=/usr/hdp/current/spark-clientexport SPARK_CONF_DIR=/etc/spark/confexport KYUUBI_LOG_DIR={{kyuubi_log_dir}}export KYUUBI_PID_DIR={{kyuubi_pid_dir}}</value><value-attributes><type>content</type></value-attributes><on-ambari-upgrade add="true"/></property></configuration>
本文件主要设置JAVA_HOME、HADOOP_CONF_DIR、KYUUBI_LOG_DIR、KYUUBI_PID_DIR等相关路径信息
2.2.2.5 编辑kyuubi-log4j-properties.xml文件

本文件主要用来配置spark ranger相关参数。
2.2.2.7 编辑ranger-spark-audit.xml文件
<?xml version="1.0"?><configuration><property><name>xasecure.audit.is.enabled</name><value>true</value><description>Is Audit enabled?</description><value-attributes><type>boolean</type></value-attributes><on-ambari-upgrade add="false"/></property><property><name>xasecure.audit.destination.db</name><value>false</value><display-name>Audit to DB</display-name><description>Is Audit to DB enabled?</description><value-attributes><type>boolean</type></value-attributes><depends-on><property><type>ranger-env</type><name>xasecure.audit.destination.db</name></property></depends-on><on-ambari-upgrade add="false"/></property><property><name>xasecure.audit.destination.db.jdbc.driver</name><value>{{jdbc_driver}}</value><description>Audit DB JDBC Driver</description><on-ambari-upgrade add="false"/></property><property><name>xasecure.audit.destination.db.jdbc.url</name><value>{{audit_jdbc_url}}</value><description>Audit DB JDBC URL</description><on-ambari-upgrade add="false"/></property><property><name>xasecure.audit.destination.db.password</name><value>{{xa_audit_db_password}}</value><property-type>PASSWORD</property-type><description>Audit DB JDBC Password</description><value-attributes><type>password</type></value-attributes><on-ambari-upgrade add="false"/></property><property><name>xasecure.audit.destination.db.user</name><value>{{xa_audit_db_user}}</value><description>Audit DB JDBC User</description><on-ambari-upgrade add="false"/></property></configuration>
本文件主要用来配置spark ranger audit 相关参数。
2.2.2.8 编辑alerts.json文件
"KYUUBI_SEVER": [{"name": "kyuubi_server_status","label": "Kyuubi Server","description": "This host-level alert is triggered if the Kyuubi Server cannot be determined to be up.","interval": 1,"scope": "ANY","source": {"type": "SCRIPT","path": "DIF/3.0/services/SPARK/package/scripts/alerts/alert_kyuubi_server_port.py","parameters": [{"name": "check.command.timeout","display_name": "Command Timeout","value": 120.0,"type": "NUMERIC","description": "The maximum time before check command will be killed by timeout","units": "seconds","threshold": "CRITICAL"}]}}]
在alert.json文件中添加检测kyuubi服务器是否启动的告警检测配置，每隔120秒检测一次kyuubi服务器服务是否正常。检测逻辑由alert_kyuubi_server_port.py实现
2.2.2.9 编辑alert_kyuubi_server_port.py文件
alert_kyuubi_server_port.py的实现逻辑可以参考alert_spark_thrift_port.py，在此不具体实现逻辑，原理就是定时执行beeline连接操作判断网站上的连接成功。
2.2.2.10 编辑kerberos.json文件
{"name": "kyuubi_service_keytab","principal": {"value": "spark/_HOST@${realm}","type" : "service","configuration": "kyuubi-defaults/kyuubi.kinit.principal","local_username" : "${spark-env/spark_user}"},"keytab": {"file": "${keytab_dir}/spark.service.keytab","owner": {"name": "${spark-env/spark_user}","access": "r"},"group": {"name": "${cluster-env/user_group}","access": ""},"configuration": "kyuubi-defaults/kyuubi.kinit.keytab"}}
在kerberos.json文件中添加自动生成principal、keytab配置到kyuubi-defaults的逻辑。在集群启动kerberos认证的时候，会自动在kyuubi-defaults中添加kyuubi.kinit.keytab及kyuubi.kinit.principal配置项。
2.2.2.11 更新 ambari-server、ambari-agent RPM
将上述修改以及添加的文件内容更新到ambari-server、ambari-agent RPM包中的相应目录中。
对于已经安装的套件，可以通过如下操作进行：
1.卸载spark服务
2.将上述添加的文件放到如下目录的位置：
/var/lib/ambari-server/resources/stacks/HDP/3.0/services/SPARK/var/lib/ambari-agent/cache/stacks/DIF/3.0/services/SPARK
3. 在ambari-serer执行sudo ambari-server restart
4. 在ambari-agent所在节点执行sudo ambari-agent restart
5. 重新安装spark服务
3、效果展示
3.1 安装效果展示
安装spark时，支持选择kyuubi服务器组件
安装过程中可以在界面上配置kyuubi参数
3.2 安装成功后效果展示
