You can also use -Dmapred.cache.archives=<hdfs:///your tar file path> to
ship the tar file using distributed cache. Hadoop will take care of
untarring the file and putting it in the current directory if the extension
is one of .zip, .tar, .tgz or .tar.gz. This is a feature of
hadoop's distributed cache.
