一、目的
为了整理离线数仓开发的全流程，算是温故知新吧
离线数仓的数据源是Kafka和MySQL数据库，Kafka存业务数据，MySQL存维度数据
采集工具是Kettle和Flume，Flume采集Kafka数据，Kettle采集MySQL数据
离线数仓是Hive
目标数据库是ClickHouse
任务调度器是海豚
二、数据采集
（一）Flume采集Kafka数据
1、Flume配置文件
## agent a1
a1.sources = s1
a1.channels = c1
a1.sinks = k1
## configure source s1
a1.sources.s1.type = org.apache.flume.source.kafka.KafkaSource
a1.sources.s1.kafka.bootstrap.servers = 192.168.0.27:9092
a1.sources.s1.kafka.topics = topic_b_queue
a1.sources.s1.kafka.consumer.group.id = queue_group
a1.sources.s1.kafka.consumer.auto.offset.reset = latest
a1.sources.s1.batchSize = 1000
## configure channel c1
## a1.channels.c1.type = memory
## a1.channels.c1.capacity = 10000
## a1.channels.c1.transactionCapacity = 1000
a1.channels.c1.type = file
a1.channels.c1.checkpointDir = /home/data/flumeData/checkpoint/queue
a1.channels.c1.dataDirs = /home/data/flumeData/flumedata/queue
## configure sink k1
a1.sinks.k1.type = hdfs
a1.sinks.k1.hdfs.path = hdfs://hurys23:8020/user/hive/warehouse/hurys_dc_ods.db/ods_queue/day=%Y-%m-%d/
a1.sinks.k1.hdfs.filePrefix = queue
a1.sinks.k1.hdfs.fileSuffix = .log
a1.sinks.k1.hdfs.round = true
a1.sinks.k1.hdfs.roundValue = 10
a1.sinks.k1.hdfs.roundUnit = second
a1.sinks.k1.hdfs.rollSize = 1200000000
a1.sinks.k1.hdfs.rollCount = 0
a1.sinks.k1.hdfs.rollInterval = 0
a1.sinks.k1.hdfs.idleTimeout = 60
a1.sinks.k1.hdfs.minBlockReplicas = 1
a1.sinks.k1.hdfs.fileType = SequenceFile
a1.sinks.k1.hdfs.codeC = gzip
## Bind the source and sink to the channel
a1.sources.s1.channels = c1
a1.sinks.k1.channel = c1
2、用海豚调度Flume任务
#!/bin/bash
source /etc/profile
/usr/local/hurys/dc_env/flume/flume190/bin/flume-ng agent -n a1 -f /usr/local/hurys/dc_env/flume/flume190/conf/queue.properties
3、目标路径
（二）Kettle采集MySQL维度数据
1、Kettle任务配置
2、用海豚调度Kettle任务
#!/bin/bash
source /etc/profile
/usr/local/hurys/dc_env/kettle/data-integration/pan.sh -rep=hurys_linux_kettle_repository -user=admin -pass=admin -dir=/mysql_to_hdfs/ -trans=23_MySQL_to_HDFS_tb_radar_lane level=Basic >>/home/log/kettle/23_MySQL_to_HDFS_tb_radar_lane_`date +%Y%m%d`.log
3、目标路径
三、ODS层
（一）业务数据表
use hurys_dc_ods;
create external table if not exists ods_queue(
queue_json string
)
comment '静态排队数据表——静态分区'
partitioned by (day string)
stored as SequenceFile
;
--刷新表分区 msck repair table ods_queue; --查看表分区 show partitions ods_queue; --查看表数据 select * from ods_queue;
（二）维度数据表
use hurys_dc_basic;
create external table if not exists tb_device_scene(

这里的ADS层，其实就是用Kettle把Hive的DWS层结果数据同步到ClickHouse中，也是一个Kettle任务而已
这样用海豚进行调度每一层的任务，整个离线数仓流程就跑起来了

3、维度数据
#! /bin/bash
source /etc/profile
hive -e "
use hurys_dc_dwd;
set hive.vectorized.execution.enabled=false;
insert overwrite table hurys_dc_dwd.dwd_holiday
select
day, holiday,year
from hurys_dc_basic.tb_holiday
group by day, holiday, year
"
（十）hive_ods（ODS层任务）
#! /bin/bash
source /etc/profile
hive -e "
use hurys_dc_ods;
msck repair table ods_queue;
msck repair table ods_turnratio;
msck repair table ods_queue_dynamic;
msck repair table ods_statistics;
msck repair table ods_area;
msck repair table ods_pass;
msck repair table ods_track;
msck repair table ods_evaluation;
msck repair table ods_event;

目前，整个离线数仓的流程大致就是这样，有问题的后面再完善！
