------------------------------
Resolution: Duplicate
> Avoid storing unnecessary information in the Memory for the finished apps
> -------------------------------------------------------------------------
>
> Key: YARN-6524
> URL: https://issues.apache.org/jira/browse/YARN-6524
> Project: Hadoop YARN
> Issue Type: Bug
> Components: RM
> Affects Versions: 2.7.3
> Reporter: Naganarasimha G R
>
> Avoid storing unnecessary information in the Memory for the finished apps
> In case of cluster with large number of finished apps, more memory is
> required to store the unused information i.e. related AM's Container launch
> like Localization resources, tokens etc.
> In one such scenario we had around 9k finished apps each with 257
> LocalResource amounting to 108 kbytes per app and just for 9k apps it was
> nearly taking ~ 0.8 GB of memory. In Low end machines this would create
> resource crunch in RM
