[jira] [Created] (MAPREDUCE-5989) Add DeletionService in AM
Varun Saxena created MAPREDUCE-5989:
---------------------------------------
Summary: Add DeletionService in AM
Key: MAPREDUCE-5989
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5989
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: applicationmaster
Reporter: Varun Saxena
Assignee: Varun Saxena
In AM, for graceful cleanup, I propose addition of a DeletionService which will do the following :
1. Cleanup of failed tasks (temporary data need not occupy space till NM's Deletion Service is invoked)
2. Staging directory deletion (During AM shutdown, its better to place staging dir cleanup in Deletion Service: Refer to MAPREDUCE-4841 )
