Subject [jira] [Commented] (YARN-5431) TimeLineReader daemon start should allow to pass its own reader opts
Date Tue, 26 Jul 2016 17:15:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15394115#comment-15394115
] 

Varun Saxena commented on YARN-5431:
------------------------------------

[~rohithsharma], I would prefer to name the opts as {{YARN_TIMELINEREADER_OPTS}} instead of
{{HADOOP_TIMELINEREADER_OPTS}} along the lines of YARN_RESOURCEMANAGER_OPTS.

Ideally HADOOP_NODEMANAGER_OPTS should also be named as YARN_NODEMANAGER_OPTS and so on. I
see in YARN-1400 only RM opts were changed but not others.
Also should we have better description for these OPTS along the lines of {{yarn-env.sh}} ?
But these issues are not related to this JIRA and a separate JIRA can be filed for it...

Moreover, timelinereader command is meant only for ATSv2 and timelineserver only for ATSv1/1.5
(i.e. depending on timeline service version you are running)
This isn't very clear from the help. Maybe we can handle this here itself. cc [~sjlee0]
