>
> TimelineCachePluginImpl generates TimelineEntityGroupId.newInstance(appId,
> appId.toString()) as an EntityGroupId for dag entities. This results entities
> in file based on application EntityGroupId to loaded by ATS during a read
> operation. This file can become very large in long running AM and causes
> timeout and delays in ATS.
> Removing this id, reduces this parsing time and prevents the application
> entities from being loaded into cache.
