Till Rohrmann created FLINK-9410:
------------------------------------

             Summary: Replace NMClient with NMClientAsync in YarnResourceManager
                 Key: FLINK-9410
                 URL: https://issues.apache.org/jira/browse/FLINK-9410
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.5.0, 1.6.0
            Reporter: Till Rohrmann
             Fix For: 1.6.0


Currently, the {{YarnResourceManager}} uses the synchronous {{NMClient}} which is called from within the main thread of the {{ResourceManager}}. Since these operations are blocking, we should replace the client with the {{NMClientAsync}} and make the calls non blocking.
