> This jira implements the new FileSystem API as proposed in HDFS-202. The new API aims
to eliminate individual "getFileBlockLocations" calls to NN for each file in the input directory
of a job. Instead, a file's block locations are returned together with FileStatus when listing
a directory, thus improving getSplits performance.
