[jira] Created: (MAPREDUCE-1703) TaskRunner would crash in finally
block if taskDistributedCacheManager is null
TaskRunner would crash in finally block if taskDistributedCacheManager is null
------------------------------------------------------------------------------
Key: MAPREDUCE-1703
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1703
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: tasktracker
Affects Versions: 0.21.0
Reporter: Amareshwari Sriramadasu
Fix For: 0.22.0
If TaskRunner throws an Exception before initializing taskDistributedCacheManager, it would crash in finally block at taskDistributedCacheManager.release(). TaskRunner would crash without doing tip.reportTaskFinished() thus not failing the task. Task will be marked FAILED after "mapred.task.timeout" because there is no report from the task.
We should add a not null check for taskDistributedCacheManager in finally block.
