You can use the Hadoop client to submit jobs to the Hadoop cluster. You might need to
optimize the Hadoop client memory allocated by to the client machine. The Hadoop client memory
is the amount of RAM utilized by the Hadoop client process and is defined in the
%HADOOP_HOME%\etc\hadoop\hadoop-env.cmd
configuration file. To set the
Hadoop client memory configuration, run the following command:
set HADOOP_CLIENT_OPTS=-XmxMemory_amount
where Memory_amount is the new RAM specification.
