Subject [jira] [Commented] (YARN-562) NM should reject containers allocated by previous RM
Date Fri, 26 Apr 2013 03:44:16 GMT

Vinod Kumar Vavilapalli commented on YARN-562:
----------------------------------------------

The latest patch looks good to me, +1. 

Agreed about setting it to say a -ve number. +1 for doing it via YARN-618, this has become
big enough already.

Thanks for the testing too. I am checking this in.

> Its possible that after RM shutdown, before AM goes down,AM still call startContainer
on NM with containers allocated by previous RM. When RM comes back, NM doesn't know whether
this container launch request comes from previous RM or the current RM. we should reject containers
allocated by previous RM
