[jira] [Created] (HDFS-15509) Set safemode should not fail if one of the namenode is down.

Leon Gao created HDFS-15509:
-------------------------------

             Summary: Set safemode should not fail if one of the namenode is down.
                 Key: HDFS-15509
                 URL: https://issues.apache.org/jira/browse/HDFS-15509
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
    Affects Versions: 3.3.0
            Reporter: Leon Gao
            Assignee: Leon Gao


When the first namenode (let's say nn0) is down, set safemode command will always fail unless users manually update the configuration. This is distracting when debugging issues.
