[jira] [Commented] (YARN-4140) RM container allocation delayed
incase of app submitted to Nodelabel partition
[ https://issues.apache.org/jira/browse/YARN-4140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14739282#comment-14739282 ]
Sunil G commented on YARN-4140:
-------------------------------
HI [~leftnoteasy]
I have a doubt here. node-label expression is set in ANY by AM. Any reason why its not updated for node-local and rack-local there itself. Could you pls help to clarify.

> Trying to run application on Nodelabel partition I found that the application execution time is delayed by 5 – 10 min for 500 containers . Total 3 machines 2 machines were in same partition and app submitted to same.
> After enabling debug was able to find the below
> # From AM the container ask is for OFF-SWITCH
> # RM allocating all containers to NODE_LOCAL as shown in logs below.
> # So since I was having about 500 containers time taken was about – 6 minutes to allocate 1st map after AM allocation.
> # Tested with about 1K maps using PI job took 17 minutes to allocate next container after AM allocation
> Once 500 container allocation on NODE_LOCAL is done the next container allocation is done on OFF_SWITCH
