Description
-------

TAJO-983: Worker should directly read Intermediate data stored in localhost 
rather than fetching

Currently, worker always fetches all intermediate via Fetcher and than store 
them in local file system even though some intermediate data already are stored 
in local file system. It is inefficient and causes unnecessary I/O and extra 
storage occupation. We should improve it.
