[jira] [Created] (YARN-5940) Change Re-Init API to use deferred RPC

Jian He created YARN-5940:
-----------------------------

             Summary: Change Re-Init API to use deferred RPC 
                 Key: YARN-5940
                 URL: https://issues.apache.org/jira/browse/YARN-5940
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Jian He


HADOOP-11552 added the functionality to allow server to handoff RPC requests and return a deferred response,  we could use this feature for re-init API where the API can block until the re-Init process is complete.  This avoids the usual polling approach for the user code to discover when the re-Init is complete.
