    Description

      $ cd src/contrib/index
      $ ant clean test

      This fails the test TestIndexUpdater due to a mismatch in the - doneFileNames - data structure, when it is being run with different parameters.

      (ArrayIndexOutOfBoundsException raised when inserting elements in doneFileNames, array ).

      Debugging further - there seems to be an additional file called as - hdfs://localhost:36021/myoutput/_SUCCESS , taken into consideration in addition to those that begins with done* . The presence of the extra file causes the error.

      Attaching a patch that would circumvent this by increasing the array length of shards by 1 .

      But longer term the test fixtures need to be probably revisited to see if the presence of _SUCCESS as a file is a good thing to begin with before we even get to this test case.

      Any comments / suggestions on the same welcome.
