Varun Saxena commented on YARN-3863:

Sorry I should say if I trim down the *columns* I get from HBase as I have done 
in YARN-3862, the *columns* required to apply those filters may not work.

> Currently filters in timeline reader will return an entity only if all the 
> filter conditions hold true i.e. only AND operation is supported. We can 
> support OR operation for the filters as well. Additionally as primary backend 
> implementation is HBase, we can design our filters in a manner, where they 
> closely resemble HBase Filters.
