Description
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
