---------------------------------
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.
