[Hue|Hive]return code 1 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
问题 Hue(4.5)查询Hive(1.2.2)的Phoenix外部表运行一段时间之后会报错 Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask 或者报错 Error while compilin
FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
hiveserver2中运行命令报错 Execution Errorreturn code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask 解决办法、 1、调大虚拟机内存，单台节点至少1G可用，调大虚拟机内存不需要关机，调小需要关机，如果上限只有XG，不能调大，关机再调，再调节MapReduce单个任务分配的内存分配的内存大小 set
