> 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
> Affects Versions: 2.0.0-alpha, 3.0.0
> 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.
