Description

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.
