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.

--localizations hdfs:///user/yarn/script1.py->algorithm1.py
/opt/script2.py->script2.py{code}
