[jira] [Created] (TEZ-992) Recovery data should not be written on AsyncDispatcher thread

Bikas Saha created TEZ-992:
------------------------------

             Summary: Recovery data should not be written on AsyncDispatcher thread
                 Key: TEZ-992
                 URL: https://issues.apache.org/jira/browse/TEZ-992
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Bikas Saha


This may block the DAG operations in case the recovery data needs to be synchronously stored. The operations requiring this blocking operation should change their state machines to wait for the store operation before moving ahead. They will move ahead after they receive notification from the RecoveryService that their operation has completed.
