Varun Saxena commented on YARN-7190:
------------------------------------
bq. hadoop-yarn-server-timelineservice-hbase-tests-3.1.0-SNAPSHOT.jar is
appearing directly under yarn folder
I had thought of moving it to test folder but as hadoop-yarn-server-tests,
which is a test project too, was also directly under yarn folder as well, so
left it as it is.
As we are going to place our jars in a separate folder, I was also thinking to
move it to a separate test folder.
bq. Are you going to place Ats1/1.5 server jars as well in this folder?
No. That would be an incompatible change for stable feature even though nobody
ideally should be using the server side jars. We should to be honest separate
out client and server jars but that would have to be discussed and handled as
part of another JIRA. As part of this JIRA, we will take care only of newly
added jars by us.

> [~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.
> Here is a list of some jars
