File be/src/util/decompress.cc:

Line 95:   *stream_end = input_length == 0;
Are you sure this is always correct thing to do given the way HdfsTextScanner::DecompressBufferStream() uses this routine.  (In terms of wanting to retry if progress was not made and also for finding malformed files -- e.g. ones without Z_STREAM_END).

Why was this added?
