      Description

      When running MapReduce with concatenated gzip files as input, only the first part ("member" in gzip spec parlance, http://www.ietf.org/rfc/rfc1952.txt) is read; the remainder is silently ignored. As a first step toward fixing that, this issue will add a configurable option to throw an error in such cases.

      MAPREDUCE-469 is the tracker for the more complete fix/feature, whenever that occurs.
