>                 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?
