      Description

      CombineFileInputFormat.getSplits() does not take into account whether a file is splittable.
      This can lead to a problem for compressed text files - for example, getSplits() may return more
      than 1 split depending on the size of the compressed file, all the splits recordreader will read the
      complete file.

      I ran into this problem while using Hive on hadoop 20.
