Subject [jira] [Commented] (YARN-422) Add NM client library
Date Mon, 06 May 2013 17:04:17 GMT

    [ https://issues.apache.org/jira/browse/YARN-422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13649869#comment-13649869

Bikas Saha commented on YARN-422:
---------------------------------

I am not contending that the behavior is wrong. I am suggesting that it should be optional
with the default set to true. If needed, it can be overridden to not do so. e.g. there is
a pending change in AMRMClient to not unregister with the RM when the RM sends a reboot command.
That is the correct behavior but it will have an override option because sometimes apps may
actually want to unregister (race between reboot and app completion).
