Subject [jira] [Updated] (YARN-4132) Nodemanagers should try harder to connect to the RM
Date Thu, 29 Oct 2015 20:28:28 GMT

     [ https://issues.apache.org/jira/browse/YARN-4132?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chang Li updated YARN-4132:
---------------------------
    Attachment: YARN-4132.3.patch

Thanks [~djp] for review and proposal! 
have updated .3 patch which let {{createRetryPolicy}} take additional parameters of retryWaitTime
and retryInterval, and only use default conf if these two parameters if not set. I also create
a new function call of {{createRMProxy}} which take these two additional parameters. I didn't
overwrite the existing {{createRMProxy}} because otherwise I need to update many of the function's
caller.
Could you help review the latest patch? Thanks!

> Being part of the cluster, nodemanagers should try very hard (and possibly never give
up) to connect to a resourcemanager. Minimally we should have a separate config to set how
aggressively a nodemanager will connect to the RM separate from what clients will do.
