Subject [jira] [Commented] (MAPREDUCE-3494) The RM should handle the graceful shutdown of the NM.
Date Thu, 01 Dec 2011 15:24:41 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13160944#comment-13160944
] 

Jonathan Eagles commented on MAPREDUCE-3494:
--------------------------------------------

A side-effect of this is that NMs using static (non-ephemeral) ports are unable to rejoin
until after the expiry period (yarn.resourcemanager.nm.liveness-monitor.expiry-interval-ms
default is 10 minutes!).

> Instead of waiting for the NM expiry, RM should remove and handle the NM, which is shutdown
gracefully.
