Hi [~rohithsharma]

IIUC this could be handle by configuring the value about 80% for 1 MB(jute buffer size). 

# Exception log could occupy space (YARN-6125 Bytes limit is added for diagnostics message ) 
# Finish time , priority, queuename can be handle by configuring lesser value

So incombination we should be able handle.

> 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.
