About documentation in apache hadoop site
Hi, I am Yoonmin from DGIST, South Korea.

 

I found some typo in

http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Clus
terSetup.html

 

In the Hadoop Startup content,

 

Run a script to start DataNodes on all slaves:

$ $HADOOP_PREFIX/sbin/hadoop-daemon.sh --config $HADOOP_CONF_DIR --script
hdfs start datanode

 

Should be modified as

$ $HADOOP_PREFIX/sbin/hadoop-daemons.sh --config $HADOOP_CONF_DIR --script
hdfs start datanode

(hadoop-daemon.sh is for master, hadoop-daemons. Is for slave when every
slave address is defined at slave file)

 

Also, Run a script to start NodeManagers on all slaves has same typo.

So, it should be modified as

$ $HADOOP_YARN_HOME/sbin/yarn-daemons.sh --config $HADOOP_CONF_DIR start
nodemanager

 

Hadoop shutdown also need to modified for above two scripts.

 

 

Thanks
