I used the command : $HADOOP_PREFIX_HOME/bin/hdfs start namenode --config $HADOOP_CONF_DIR
to sart HDFS. This command is in Hadoop document (here <http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/ClusterSetup.html>) However, I got errors as Exception in thread "main" java.lang.NoClassDefFoundError:start Could anyone tell me how to start and stop HDFS? By the way, how to set Gmail so that it doesn't top post my reply?
