> 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.
