Joep Rottinghuis commented on YARN-7190:
----------------------------------------
Yeah, this is a legit issue. Having these jars in a separate folder seems to be
a good idea. Then we'll just modify the NM classpath to add this folder and we
should be good.
Possibly other jars can be moved to this separate folder as well, but that
could become a backwards compatibility issue, so we should leave that to a
separate jira.
Note that findbugs-annotations-1.3.9-1.jar should be needed for build/test only
and doesn't need to be shipped on the runtime classpath
> Ensure only NM classpath in 2.x gets TSv2 related hbase jars, not the user
> classpath

> [~jlowe] had a good observation about the user classpath getting extra jars
> in hadoop 2.x brought in with TSv2. If users start picking up Hadoop 2,x's
> version of HBase jars instead of the ones they shipped with their job, it
> could be a problem.
> So when TSv2 is to be used in 2,x, the hbase related jars should come into
> only the NM classpath not the user classpath.
