---------------------------------
Summary: Provide a mechanism for cleaning config items from
LocalDirAllocator which will not be used anymore
Key: HADOOP-8578
URL: https://issues.apache.org/jira/browse/HADOOP-8578
Project: Hadoop Common
Issue Type: Improvement
Reporter: Devaraj K
If we use DefaultContainerExecutor, for every application one config item is
getting added into the LocalDirAllocator.contexts and is not deleting forever
and due to this nm throws oom error after some time. This has been fixed with
MAPREDUCE-4379 by adding removeContext() api in LocalDirAllocator and explictly
deleting after the application completion.
It would be good if we can clean the cache of config items from
LocalDirAllocator when there is no use with that furthermore.
