---------------------------------

             Summary: Need to implement listLocatedStatus() in ProxyFileSystem
                 Key: HIVE-5070
                 URL: https://issues.apache.org/jira/browse/HIVE-5070
             Project: Hive
          Issue Type: Bug
          Components: CLI
    Affects Versions: 0.11.0
            Reporter: shanyu zhao


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:

[junit] Running org.apache.hadoop.hive.cli.TestCliDriver
    [junit] Begin query: allcolref_in_udf.q
