Subject [jira] [Commented] (YARN-7190) Ensure only NM classpath in 2.x gets TSv2 related hbase jars, not the user classpath
Date Fri, 16 Mar 2018 18:26:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16402316#comment-16402316
] 

Lei (Eddy) Xu commented on YARN-7190:
-------------------------------------

Hmm, I am in the process of releasing 3.0.1,  and this JIRA comes out as incompatible in the
release changelist, so it was the revert. I feel that it is completely necessary for 3.1 /
2.9, but maybe not so for a minor release like 3.0.1. I am trying to only include bugfix and
compatible improvements in 3.0.1 now.
Does it make sense?

> [~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.
