> When running MapReduce with concatenated gzip files as input only the first part is read,
which is confusing, to say the least. Concatenated gzip is described in http://www.gnu.org/software/gzip/manual/gzip.html#Advanced-usage
and in http://www.ietf.org/rfc/rfc1952.txt. (See original report at http://www.nabble.com/Problem-with-Hadoop-and-concatenated-gzip-files-to21383097.html)
