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

                 Key: HADOOP-523
                 URL: http://issues.apache.org/jira/browse/HADOOP-523
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.6.0
            Reporter: Sanjay Dahiya
         Assigned To: Owen O'Malley
             Fix For: 0.7.0


With hadoop 0.6.1, TextInputFormat fails with NullPointerException, causing Job with fail.


TextInputFormat.configure() is not called to initialize compressionCodecs and following method
throws NullPointerException.

  protected boolean isSplitable(FileSystem fs, Path file) {
    return compressionCodecs.getCodec(file) == null;
  }
