    MAPREDUCE-7120. 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.
