The "->" means we want the original File in the left to be localized to a named File in
the right.

This example below means the job wants two files to be localized. The first is "hdfs:///user/yarn/script1.py"
to be localized into worker's dir and named "algorithm1.py", and the second local file "/opt/script2.py"
to be localized into worker's dir as "script2.py".

The underlying differences is that we don't upload "hdfs:///.." to HDFS again.
{code:java}
--localizations hdfs:///user/yarn/script1.py->algorithm1.py /opt/script2.py->script2.py{code}
