Date Wed, 05 Feb 2014 17:58:16 GMT


Lewis John McGibbney commented on NUTCH-1556:

Hi [~ksmets], this issue has been addressed and resolved. 
Do you care to submit your comments or a patch for NUTCH-1679?
Also can you explain more verbosely what you mean by 
bq. this causes a lot of refetched pages
Do you mean that this causes a lot of fetched pages to be overwritten and refetched?

I put together a patch. it seems to be working ( it does skip the rows that do not match the
batchId), but I am worried if and how it might affect the sorting in the reduce part. anyway
check it out.
