Subject [jira] [Created] (YARN-6825) RM quit due to ApplicationStateData exceed the limit size of znode in zk
Date Fri, 14 Jul 2017 09:04:01 GMT
Rohith Sharma K S created YARN-6825:

             Summary: RM quit due to ApplicationStateData exceed the limit size of znode in
                 Key: YARN-6825
                 URL: https://issues.apache.org/jira/browse/YARN-6825
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
            Reporter: Rohith Sharma K S

YARN-5006 fixes this issue by strict validation for ApplicationStateData length against 1MB(default
max jute buffer) during application submission only. There is possibility of thrashing as
dead zone was not properly defined/taken care.

But it do not consider scenarios where ApplicationStateData can be increased later point of
time i.e 
# If app is submitted with less than 1MB during submission, later updated like queue name
or life time value or priority is changed. The app update call will be sent to statestore
which cause same issue because ApplicationStateData length has increased.
# Consider there is no app update, but final state are stored in ZK. This adds up several
fields such finishTime, finalState, finalApplicationState. This increases size of ApplicationStateData.
