Oscar Gothberg commented on HADOOP-5014:
----------------------------------------
Thanks Tom for filing the Jira on this issue.
Does anyone know a possible alternate gzip codec that could just be plugged
into Hadoop? I suddenly have terabytes of gzipped data that I don't know if I
can trust hadoop with, and it would be a big pain to re-archive everything.

> Key: HADOOP-5014
> URL: https://issues.apache.org/jira/browse/HADOOP-5014
> Project: Hadoop Core
> Issue Type: Improvement
> Components: io, mapred
> Affects Versions: 0.17.0, 0.19.0
> Reporter: Tom White
>
> 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)
