--------------------------------------

             Summary: RM container allocation delated incase of app submitted to Nodel partition
                 Key: YARN-4140
                 URL: https://issues.apache.org/jira/browse/YARN-4140
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bibin A Chundatt
            Assignee: Bibin A Chundatt


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 allocated
map after AM allocation.
#Tested with about 1K maps with PI job took 17 minutes to allocated the next container after
AM allocation

Once 500 container allocation on NODE_LOCAL is done the next container allocation is done
on OFF_SWITCH
