Subject [jira] [Created] (HDFS-14549) EditLogTailer shouldn't output full stack trace when interrupted
Date Wed, 05 Jun 2019 17:45:00 GMT
Íñigo Goiri created HDFS-14549:
----------------------------------

             Summary: EditLogTailer shouldn't output full stack trace when interrupted
                 Key: HDFS-14549
                 URL: https://issues.apache.org/jira/browse/HDFS-14549
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Íñigo Goiri


Currently, when the NN transitions to active, it interrupts the EditLogTailer and outputs
the full stack trace.

I don't think this adds any value and it should just print the message.
