Description

MAPREDUCE-1981 introduced a new API for FileSystem - listLocatedStatus. It is used in Hadoop's FileInputFormat.getSplits(). Hive's ProxyFileSystem class needs to implement this API in order to make Hive unit test work.

Otherwise, you'll see these exceptions when running TestCliDriver test case, e.g. results of running allcolref_in_udf.q:
