Bibin A Chundatt commented on YARN-8972:
----------------------------------------
Over all the patch looks good to me .
One concern is regarding the default value. ZK by default limit is 1MB of znode
rt ? So should we reduce default to less than max allowed limit.ex : 80% of max
ApplicationstateData written to zk contains at RM contains additional fields
like timeoutdata,diagnostics etc.
