[jira] [Created] (HDFS-5421) Not need to launch Secondary namenode for NN HA mode?

Raymond Liu created HDFS-5421:
---------------------------------

             Summary: Not need to launch Secondary namenode for NN HA mode?
                 Key: HDFS-5421
                 URL: https://issues.apache.org/jira/browse/HDFS-5421
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: scripts
            Reporter: Raymond Liu
            Priority: Minor


For Hadoop 2, When deploying with NN HA, the wiki says that it is an error to start a secondary namenode. While the sbin/start-dfs.sh still launch a secondary namenode even nothing related to the secondary namenode is configured. Should this be fixed? or people just don't use this scripts to start HA hdfs?
