Subject [jira] [Commented] (YARN-7190) Ensure only NM classpath in 2.x gets TSv2 related hbase jars, not the user classpath
Date Wed, 13 Dec 2017 16:35:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16289489#comment-16289489

Rohith Sharma K S commented on YARN-7190:
-----------------------------------------

[~varun_saxena]! Could you take a look at previous comment? This has been pending for long
time and we need push to Hadoop-3 asap otherwise we need to hurry at release time. However
we are already missing into Hadoop-3 GA release! cc :/[~vrushalic]

> [~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

> commons-csv-1.0.jar
> commons-el-1.0.jar
> commons-httpclient-3.1.jar
