Subject [jira] [Commented] (YARN-4132) Nodemanagers should try harder to connect to the RM
Date Fri, 20 Nov 2015 21:30:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-4132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15018848#comment-15018848

Jason Lowe commented on YARN-4132:
----------------------------------

Thanks for updating the patch!  I think we're close.

* The property docs should mention the fallback if unspecified, otherwise it's confusing to
have no specified value in yarn-default
* The new createRetryPolicy method simply can be private and therefore doesn't need the decorators
indicating it is
* Nit: new createRetryPolicy overload should have Configuration as first parameter for consistency
with existing method.

> 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.
