Actually I started to play with the latest release 0.23.0 on two nodes
yesterday. And it was easy to start the hdfs. However it took me a while to
configure the yarn. I set the variables HADOOP_COMMON_HOME to where you
extracted the tarball and HADOOP_HDFS_HOME to the local dir where I pointed t
Try $HADOOP_PREFIX_HOME/bin/hdfs namenode stop --config $HADOOP_CONF_DIR and
$HADOOP_PREFIX_HOME/bin/hdfs datanode stop --config $HADOOP_CONF_DIR. It would
stop namenode and datanode separately.
The HADOOP_CONF_DIR is the directory where you store your configuration files.
