Summary: 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
