Greg Roelofs commented on MAPREDUCE-469:
----------------------------------------
Okey dokey, default it is. mapreduce-user feedback was limited but in favor of
hardcoding it (i.e., not even configurable), so that's currently my plan for
the final version. Later today I'll post a second interim version that merely
flips the current config option. (Main purpose will be to incorporate informal
review feedback from Chris Douglas and, hopefully, make the unit test much more
complete; at that point I'll consider it ready for formal review and checkin.)

> 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)
