> I am using Hadoop Streaming to analyze Wikipedia data files, which are in XML format
and are compressed because they are so large.  While doing some preliminary tests, I discovered
that you cannot use StreamXMLRecordReader with gzipped data files -- the data is fed into
the mapper script as raw data.
