> Key: HADOOP-7799
> URL: https://issues.apache.org/jira/browse/HADOOP-7799
> Project: Hadoop Common
> Issue Type: Bug
> Components: documentation
> Affects Versions: 0.23.0
> Reporter: Eric Payne
> Assignee: Arun C Murthy
> Attachments: ClusterSetup.html.patch
>
>
> - In section +Prerequisites+
> -- Please add a link to download locaion of 0.23 release tar-ball.
> - In section +Installation+
> -- It would be good to have more details about where they should "untar" the
> image and what the directory structure should look like. I can provide my
> notes on the detailed steps I took to successfully install.
> - In the section +Running Hadoop in Non-Secure Mode+
> -- Can you add that templaces for the site and environment files can be found
> in {{./conf/}}, {{./share/hadoop/common/templates/conf/}}, and
> {{./share/hadoop/hdfs/templates/conf/}}
> -- Also, it might be good to add a link to a sample configs that contain the
> bare minumum to start a cluster.
> -- The +conf/hdfs-site.xml+ section references the {{dfs.datanode.data.dir}}
> property. Should we also include a reference to the
> {{dfs.datanode.data.dir.perm}} property as well?
> -- The +Hadoop Rack Awareness+ section references
> {{topology.node.switch.mapping.impl}}, but I think this is deprecated. I
> think the new one is {{net.topology.node.switch.mapping.impl}}. Also,
> {{topology.script.file.name}} seems to be deprecated in favor of
> {{net.topology.script.file.name}}.
> - In section +Operating the Hadoop Cluster+
> -- The HDFS format command should have the {{-clusterid}} parameter:
> --- {{$HADOOP_PREFIX_HOME/bin/hdfs namenode -format -clusterid
> <cluster_name>}}
> -- The command to start the namenode is incorrect. It should either be:
> 1. {{$HADOOP_PREFIX_HOME/bin/hdfs --config $HADOOP_CONF_DIR namenode &}} ##
> without the {{start}}
> or
> 2. {{$HADOOP_PREFIX/sbin/hadoop-daemon.sh --config $HADOOP_CONF_DIR start
> namenode}}
> I prefer the second, since you can also use that to stop the daemon.
> -- The same for the command to start the datanode
> -- The same for the command to start the resourcemanager, historyserver, and
> nodemanagers, except that it should be {{yarn-daemon.sh}}
> - Hadoop Shutdown:
> -- If stopping the daemons is required, then {{hadoop-daemon.sh}} and
> {{yarn-daemon.sh}} should be used to both start and stop.
