Greg Roelofs resolved MAPREDUCE-1795.
-------------------------------------
Resolution: Won't Fix
Per previous comment, we're going to fix the underlying issue instead (i.e.,
make decompressors support concatenated streams). See MAPREDUCE-469.
> add error option if file-based record-readers fail to consume all input
> (e.g., concatenated gzip, bzip2)

> Key: MAPREDUCE-1795
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1795
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Reporter: Greg Roelofs
> Assignee: Greg Roelofs
>
> 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.
