Hairong Kuang commented on HADOOP-6870:
---------------------------------------
FileStatus uses a very loose equality semantics. It compares only path names.
So I decided that LocatedFileStatus uses the same semantics.
> Add FileSystem#listLocatedStatus to list a directory's content together with
> each file's block locations

> 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.
