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

interrupted
Key: HDFS-14549
URL: https://issues.apache.org/jira/browse/HDFS-14549

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.
