> Project: Flink
> Issue Type: Improvement
> Components: Distributed Coordination

>
> Do not requestPartitionState from JM on partition request fail, which may
> generate too many RPC requests and block JM.
> We gain little benefit to check what state producer is in, which in the other
> hand crash JM by too many RPC requests. Task could always
> retriggerPartitionRequest from its InputGate, it would be fail if the
> producer has gone and succeed if the producer alive. Anyway, no need to ask
> for JM for help.
