Subject [jira] [Commented] (YARN-7190) Ensure only NM classpath in 2.x gets TSv2 related hbase jars, not the user classpath
Date Thu, 28 Sep 2017 16:31:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-7190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16184400#comment-16184400

Vrushali C commented on YARN-7190:

Thanks Varun for the jar sorting.

I think we should remove any extra jars that TSv2 is adding to user classpath, not just hbase
jars, unless we need those. This is for both branch 2 and trunk. I think keeping the classpath
clean as far as possible should be a general goal for all modules. 

Also, I am wondering about findbugs-annotations. Which code uses that..

> [~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.
