             Summary: Standby NN while transitioning to active throws a connection refused error when the prior active NN process is suspended
                 Key: HDFS-6089
                 URL: https://issues.apache.org/jira/browse/HDFS-6089
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: ha
    Affects Versions: 2.4.0
            Reporter: Arpit Gupta
            Assignee: Jing Zhao


The following scenario was tested:

* Determine Active NN and suspend the process (kill -19)
* Wait about 60s to let the standby transition to active
* Get the service state for nn1 and nn2 and make sure nn2 has transitioned to active.


What was noticed that some times the call to get the service state of nn2 got a socket time out connection.
