files for a job, this is a URL that also supports creating an alias for the
archive if a URL fragment is specified. For example,

necessary YARN, HDFS, and Hadoop Common jars and all other dependencies. In
that case, <<<mapreduce.application.classpath>>> would be configured to
something like the following example, where the archive basename is
hadoop-mapreduce-2.1.1.tar.gz and the archive is organized internally similar
to the standard Hadoop distribution archive:
hadoop-mapreduce-${project.version}.tar.gz and the archive is organized
internally similar to the standard Hadoop distribution archive:

Another possible approach is to have the archive consist of just the
MapReduce jars and have the remaining dependencies picked up from the Hadoop
distribution installed on the nodes. In that case, the above example would
change to something like the following:
