    [ https://issues.apache.org/jira/browse/YARN-6825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16089630#comment-16089630

Feng Yuan commented on YARN-6825:

Hi all, if we could handle this problem like YARN-5006?
Do the same size check at applicationUpdate,attemptAdd,attemptUpdate operations like YARN-5006

>                 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.
