Vrushali C commented on YARN-6094:
----------------------------------
Yes tags require hfile3 format. HBase 1.0 onwards hfile3 is the default I
believe https://issues.apache.org/jira/browse/HBASE-9801.
But yes we can add to the documentation that timeline service uses cell tags
and hence needs hfile3.
> Update the coprocessor to be a dynamically loaded one

> 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.
