Andrew Wang updated HDFS-5304:
------------------------------
Attachment: hdfs-5304-1.patch
Patch attached, wasn't that bad. Added a boolean array to {{LocatedBlock}}
which indicates if the location at the same index is cached. Added new checks
to an existing test to validate.
> Expose if a block replica is cached in getFileBlockLocations
