------------------------------------

             Summary: Add HA capabilities to YarnResourceManager
                 Key: FLINK-7805
                 URL: https://issues.apache.org/jira/browse/FLINK-7805
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination, YARN
    Affects Versions: 1.4.0
            Reporter: Till Rohrmann


The new {{YarnResourceManager}} implementation does not retrieve allocated containers from previous attempts in HA mode like the old {{YarnFlinkResourceManager}} did. We should add this functionality in order to properly support long running Yarn applications [1].
