Chang Li commented on YARN-3267:
--------------------------------

[~pramachandran] Could you take a look at my solution in my wip patch, I tried to solve this problem by pass a functor into the getEntities()call in TimelineReader, and inside LeveldbTimelineStore I check  acl before add each entity. 
Also I am about to write a unit test, where should I put this unit test?

Thanks

> While fetching the entities from timelineserver, the limit is applied on the entities to be fetched from leveldb, the ACL filters are applied after this (TimelineDataManager.java::getEntities). 
> this could mean that even if there are entities available which match the query criteria, we could end up not getting any results.
