Subject [jira] [Commented] (YARN-4597) Add SCHEDULE to NM container lifecycle
Date Fri, 15 Jan 2016 20:34:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-4597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15102431#comment-15102431
] 

Arun Suresh commented on YARN-4597:
-----------------------------------

+1 to the idea [~chris.douglas]. Agree that it would simplify some design choices we make
for modification to the {{ContianersMonitor}} and {{ContainerManager}} side for YARN-2877.
Would love to help out with this (I'd even volunteer to take a first crack at it since it
directly impacts our Distributed Scheduling work)

> Currently, the NM immediately launches containers after resource localization. Several
features could be more cleanly implemented if the NM included a separate stage for reserving
resources.
