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 -->
