Raymond Liu created HDFS-5422:
---------------------------------
Summary: Not need to launch Secondary namenode for NN HA mode?
Key: HDFS-5422
URL: https://issues.apache.org/jira/browse/HDFS-5422
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?
