> Dennis reported:
> {quote}
> In the SegmentMerger.java file about line 150 we have this:
> final SequenceFile.Reader reader =
> new SequenceFile.Reader(FileSystem.get(job), fSplit.getPath(),
> job);
> Then about line 166 in the record reader we have this:
> boolean res = reader.next(key, w);
> If I am reading that right, that would mean that the map tap would loop
> over all records for a given file and not just a given split.
> {quote}
> Right, this should instead use SequenceFileRecordReader that already has the
> logic to handle splits. Patch coming shortly - thanks for spotting this! This
> could be the reason for "out of disk space" errors that many users reported.
