[jira] [Created] (HDFS-6897) If DatanodeThreshold is not set up, do not show information regarding DatanodeThreshold during NN startup

Benoy Antony created HDFS-6897:
----------------------------------

             Summary: If DatanodeThreshold is not set up, do not show information regarding DatanodeThreshold during NN startup
                 Key: HDFS-6897
                 URL: https://issues.apache.org/jira/browse/HDFS-6897
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 2.5.0
            Reporter: Benoy Antony
            Assignee: Benoy Antony
            Priority: Minor


During Namenode startup, we see the following message:
{code}
The number of live datanodes XXX has reached the minimum number 0. Safe mode will be turned off automatically once the thresholds have been reached.
{code}
We have not setup the datanode threshold. So this message is not necessary.
It may be good to turn off this message if datanode threshold is not setup.
