Hadoop Flags:Reviewed
The timeline service v2 code base on yarn now uses hbase 1.2.4 after YARN-5976.
With this version of hbase, system classes (starting with org.apache.hadoop) can be loaded as table level coprocessors. Hence we should update the timeline service coprocessor to be a dynamically loaded one instead of static loading.
This involves code changes as well as documentation updates for deployment.
