             Summary: Interrupted execption printed out from DatanodeStateMachine
                 Key: HDDS-4233
                 URL: https://issues.apache.org/jira/browse/HDDS-4233
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
            Reporter: Marton Elek
            Assignee: Marton Elek


A strange exception is visible in the log during normal run:

{code}
2020-09-10 11:31:41 WARN  DatanodeStateMachine:245 - Interrupt the execution.
java.lang.InterruptedException: sleep interrupted
        at java.lang.Thread.sleep(Native Method)
        at org.apache.hadoop.ozone.container.common.statemachine.DatanodeStateMachine.start(DatanodeStateMachine.java:243)
        at org.apache.hadoop.ozone.container.common.statemachine.DatanodeStateMachine.lambda$startDaemon$0(DatanodeStateMachine.java:405)
        at java.lang.Thread.run(Thread.java:748)
{code}


The most common reason to this is triggering a new HB request.

As this is a normal behavior we shouldn't log exception on WARN level.
