Description

In some cases, When MapredLocalTask fails around Child process start time, we can not find the detail error information anywhere(not in strerr log, no MapredLocal log file). All we get is :

******************* ERROR org.apache.hadoop.hive.ql.exec.Task: [HiveServer2-Background-Pool: Thread-****]: Execution failed with exit status: 1
******************* ERROR org.apache.hadoop.hive.ql.exec.Task: [HiveServer2-Background-Pool: Thread-****]: Obtaining error information
******************* ERROR org.apache.hadoop.hive.ql.exec.Task: [HiveServer2-Background-Pool: Thread-****]: 
Task failed!
Task ID:
  Stage-48

Logs:

******************* ERROR org.apache.hadoop.hive.ql.exec.Task: [HiveServer2-Background-Pool: Thread-****]: /var/log/hive/hadoop-cmf-hive1-HIVESERVER2-t.log.out
******************* ERROR org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask: [HiveServer2-Background-Pool: Thread-****]: Execution failed with exit status: 1

It is really hard to debug.
