 MR task should prevent report error to AM when process is shutting down

 Key: MAPREDUCE-6002
 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6002
 Project: Hadoop Map/Reduce
  Issue Type: Bug
  Components: task
Affects Versions: 2.5.0
Reporter: Wangda Tan

 Fix For: 2.5.0

 Attachments: MR-6002.patch


 With MAPREDUCE-5900, preempted MR task should not be treat as failed. 
 But it is still possible a MR task fail and report to AM when preemption take 
 effect and the AM hasn't received completed container from RM yet. It will 
 cause the task attempt marked failed instead of preempted.
 An example is FileSystem has shutdown hook, it will close all FileSystem 
 instance, if at the same time, the FileSystem is in-use (like reading split 
 details from HDFS), MR task will fail and report the fatal error to MR AM. An 
 exception will be raised:

 We should prevent this, because it is possible other exceptions happen when 
 shutting down, we shouldn't report any of such exceptions to AM.
