Hive问题：Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
hive执行过程中报错，抓重点（黄色）：
2019-02-01 09:56:54,623 ERROR [pool-7-thread-4] dao.IHiveDaoImpl - java.sql.SQLException: org.apache.hive.service.cli.HiveSQLException:

大概是执行mapreduce的时候的错误：
查看了下mapreduce确实是执行了，
拉取mr错误日志：

看下黄色部分，可知是hbase的对应实体类错误。
原因：是修改了hbase数据字典表中的类型 -> 没有更新hive的jar包。
