Brandon Scheller updated MAPREDUCE-7120:
----------------------------------------
    Description: 
Make hadoop consider wildcard host as datalocal.

This allows hadoop to treat "\*" as data local. This allows remote filesystems to increase
performance by skipping retrys for data locality by returning "\*" as the block host when
the filesystem is asked for the block location.

Make hadoop consider wildcard host as datalocal.
