> org.apache.mahout.text.ChunkedWriter has a bug, that causes data loss, if the
> maximal chunk size is reached. The first chunk is overwritten, then it
> continues normally.
> This is caused in line 58:
> writer = new SequenceFile.Writer(fs, conf, getPath(currentChunkID++),
> Text.class, Text.class);
> The fix should look like this:
> writer = new SequenceFile.Writer(fs, conf, getPath(++currentChunkID),
> Text.class, Text.class);
