Varun Saxena commented on YARN-3863:
------------------------------------
To aid in review, I will jot down what has been done in this JIRA.
# The intention is to convert filters which were represented as maps or sets to
TimelineFilterList which would help in complex filters being supported.
i.e. Let me take example of config filters in the format {{cfg1=value1,
cfg2=value2, cfg3=value3, cfg4=value4}} which means all the key value pairs
should be matched for an entity. With work in this JIRA,we can support complex
filters such as {{(cfg1=value1 OR cfg2=value2) AND (cfg3 !=value3 AND
cfg4!=value4)}}.

> 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.
