Subject [jira] [Commented] (YARN-1368) Common work to re-populate containers’ state into scheduler
Date Wed, 07 May 2014 07:46:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-1368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13991571#comment-13991571
] 

Wangda Tan commented on YARN-1368:
----------------------------------

[~jianhe], thanks for your reply, only one comment on your reply, others make sense to me,
bq. That’s half way code, we eventually want to merge the common code of FSSchedulerNode
and FicaSchedulerNode into a common base AbstractSchedulerNode.
I think is it better to finish YARN-2017 before commit this JIRA? Otherwise we will have lots
of additional merge works to do.

> YARN-1367 adds support for the NM to tell the RM about all currently running containers
upon registration. The RM needs to send this information to the schedulers along with the
NODE_ADDED_EVENT so that the schedulers can recover the current allocation state of the cluster.
