Subject [jira] [Commented] (YARN-3554) Default value for maximum nodemanager connect wait time is too high
Date Mon, 04 May 2015 18:21:07 GMT

    [ https://issues.apache.org/jira/browse/YARN-3554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14526983#comment-14526983

Jason Lowe commented on YARN-3554:
----------------------------------

Ah, thanks [~Naganarasimha], sorry I missed that.  We can continue discussing the proper RM
connect wait time over at YARN-3518, as obviously I cannot keep them straight here. ;-)

Are there still objections to lowering it from 15 mins to 3 mins?  I'm +1 for the second patch,
but I'll wait a few days before committing to give time for alternate proposals.

> The default value for yarn.client.nodemanager-connect.max-wait-ms is 900000 msec or 15
minutes, which is way too high.  The default container expiry time from the RM and the default
task timeout in MapReduce are both only 10 minutes.
