Rohith Sharma K S commented on YARN-8512:
-----------------------------------------

Attached the patch with following modifications to update FlowContext in ApplicationImpl
 # _if_ ApplicationImpl reference found in context while starting master container _then_
 ** create new reference to ApplicationImpl
 ** update the context.
 ** update the NMStateStore so that NM recovery will pick newer ApplicationImpl.
