["Rohith Sharma K S (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-8397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16501568#comment-16501568 ] 

Rohith Sharma K S commented on YARN-8397:
-----------------------------------------

This is due to ActivitiesManager#serviceStop interrupt the thread and come out. But exception handling in run method ignores exception and continue in loop.
{code}
    cleanUpThread = new Thread(new Runnable() {
      @Override
      public void run() {
        while (true) {
          // some code
          try {
            Thread.sleep(5000);
          } catch (Exception e) {
            // ignore
          }
        }
      }
    });
{code}
