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

             Summary: Do not throw exception if YARN Application switched to FINISHED immediately after deployed in YarnClusterDescriptor#startAppMaster
                 Key: FLINK-15297
                 URL: https://issues.apache.org/jira/browse/FLINK-15297
             Project: Flink
          Issue Type: Bug
          Components: Deployment / YARN
            Reporter: Zili Chen
            Assignee: Zili Chen


Currently we throw an exception in {{YarnClusterDescriptor#startAppMaster}} if we first detect {{FINISHED}} before {{RUNNING}}. However, it is possible a legal state that the application finished normally immediately.

Right now we always try to connect the Dispatcher so it may be fine to throw the exception a bit earlier(otherwise when connect to a closed cluster an exception thrown also), but it is semantically wrong. Internally we have a code path that only required to report the ApplicationReport and it causes trouble.
