--------------------------------------------------------------------------------------------------------

                 Key: HADOOP-6870
                 URL: https://issues.apache.org/jira/browse/HADOOP-6870
             Project: Hadoop Common
          Issue Type: New Feature
          Components: fs
    Affects Versions: 0.22.0
            Reporter: Hairong Kuang
            Assignee: Hairong Kuang
             Fix For: 0.22.0


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.
