  Take a pass at putting together basic configuration settings for your cluster. Some of the
settings that follow are required, others are recommended for more straightforward and predictable
operation.
  
   * '''Hadoop Environment Settings''' - Ensure that {{{JAVA_HOME}}} is set in {{{hadoop-env.sh}}}
and points to the Java installation you intend to use. You can set other environment variables
in {{{hadoop-env.sh}}} to suit your requirments. Some of the default settings refer to the
variable {{{HADOOP_HOME}}}. The value of {{{HADOOP_HOME}}} is automatically inferred from
the location of the startup scripts. {{{HADOOP_HOME}}} is the parent directory of the {{{bin}}}
directory that holds the Hadoop scripts. In this instance it is {{{$HADOOP_INSTALL/hadoop}}}.
-  * '''Jobtracker and Namenode settings''' - Figure out where to run your namenode and jobtracker.
Set the variable {{{fs.default.name}}} to the Namenodes intended host:port. Set the variable
{{{mapred.job.tracker}}} to the jobtrackers intended host:port. These settings should be in
{{{hadoop-site.xml}}}. You may also want to set one or more of the following ports (also in
{{{hadoop-site.xml}}}):
