[jira] [Created] (FLINK-2629) Refactor YARN ApplicationMasterActor to use the async AM<-->RM client

Robert Metzger created FLINK-2629:
-------------------------------------

             Summary: Refactor YARN ApplicationMasterActor to use the async AM<-->RM client 
                 Key: FLINK-2629
                 URL: https://issues.apache.org/jira/browse/FLINK-2629
             Project: Flink
          Issue Type: Improvement
          Components: YARN Client
    Affects Versions: 0.10
            Reporter: Robert Metzger


YARN also offers an async client for the AM <--> RM communication: https://hadoop.apache.org/docs/r2.6.0/api/org/apache/hadoop/yarn/client/api/async/AMRMClientAsync.html

Currently, container failures can block the entire JobManager actor systems for a few seconds because of blocking AM <---> RM calls.
