Hi Adarsh,
Please check start-dfs.sh
You will find
"$bin"/hadoop-daemon.sh --config $HADOOP_CONF_DIR start namenode $nameStartOpt
"$bin"/hadoop-daemons.sh --config $HADOOP_CONF_DIR start datanode $dataStartOpt
"$bin"/hadoop-daemons.sh --config $HADOOP_CONF_DIR --hosts masters start
secondarynamenode
Default secondarynamenode is run on "masters".
You can change this shell, such as you can change the last row:
"$bin"/hadoop-daemons.sh --config $HADOOP_CONF_DIR --hosts secondarynamenode
start secondarynamenode
Create a file "conf/secondarynamenode" & list machine name in it.
Best,
Xiujin Yang.
