[jira] [Created] (HDFS-4690) Namenode exits if entering safemode while secret manager is edit logging

Daryn Sharp created HDFS-4690:
---------------------------------

             Summary: Namenode exits if entering safemode while secret manager is edit logging
                 Key: HDFS-4690
                 URL: https://issues.apache.org/jira/browse/HDFS-4690
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode, security
    Affects Versions: 0.23.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp
            Priority: Critical


Going into safemode involves stopping the secret manager's thread.  An interrupt is sent to this thread.  If this occurs while the thread is logging an edit, the resulting exception in the thread will cause the NN to exit.

The fix is to back-port a subset of HDFS-2579 which went into branch 2 & trunk.
