在hive中添加加密udf,测试报错：

select encrypt_sm2("aa","04AD9356466C7A505B3B2E18F2484E1F096108FA19C0F61C707A808EDF7C132BC3CE33E63D2CC6D77FB0A172004F8F5282CEADE22ED9628A02FE8FD85AF1EFE8B3");

加密算法包版本：

<dependency>
            <groupId>org.bouncycastle</groupId>
            <artifactId>bcprov-jdk15on</artifactId>
            <version>1.57</version>
        </dependency>

根据异常，发现方法调用没权限，本地测试是正常的，猜测应该是包冲突了；

linux上查看是否有其他jar包：

locate bcprov

 

发现hadoop lib里有该jar包,版本不一致，变更版本后，有些方法不兼容了，遂查询了下是否兼容两个包的方法；

找了下，可以变更下包名，兼容加载：

<plugin>
      <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-shade-plugin</artifactId>
			 <version>3.2.1</version>
			 <configuration>
             <!-- 改为true -->  
			 <createDependencyReducedPom>true</createDependencyReducedPom>
			 </configuration>
			 <executions>
				 <execution>
					 <!-- Maven 的生命周期 -->
					 <phase>package</phase>
					 <goals>
					 <!-- 插件目标 -->
					 <goal>shade</goal>
					 </goals>
		    <configuration>
				<!-- <minimizeJar>true</minimizeJar>-->
				 <!-- 配置多版本 jar 包中类路径的重命名
 					-->
			 <relocations>
