Error while processing statement: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
这个错比较低级，只是自己没加包导致
排查过程
1、看日志

2、这里也没看到，继续找
点一下here
找到了，也是一堆信息，关键点

3、少包，加包，hive里加
找一下包在哪里

要全局生效还需要做配置
新建目录/etc/hive/ext
复制hive-hcatalog-core-2.1.1-cdh6.3.1.jar 到该目录下
配置HIVE_AUX_JARS_PATH

重启生效
