Andrzej Bialecki commented on NUTCH-392:
-----------------------------------------
Re: Content versioning - we can use negative int values as version numbers. I'm
still not sure what is the impact of BLOCK compression on MapFile random access.
Regarding the sizes: parse_text_record size is larger, because for small chunks
of data the compression overhead may far outweigh the compression gains. Re:
the large size of crawl_parse - is this related to your patch? It could be
simply related to the fact that there are many outlinks in those pages ... Or
is crawl_parse using BLOCK compression too?

> OutputFormat implementations should pass the Progressable they are passed to
> underlying SequenceFile implementations. This will keep reduce tasks from
> timing out when block writes are slow. This issue depends on
