Description

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?
