Hi, Where do I find the log of what reducer key is causing the last reducer to go on for hours? The reducer logs don't say much about the key its processing. Is there a way to enable a debug mode where it would log the key it's processing?
My query looks like: select partner_name, dates, sum(coins_granted) from table1 u join table2 p on u.partner_id=p.id group by partner_name, dates My uncompressed size of table1 is about 30GB. -Ayon See My Photos on Flickr Also check out my Blog for answers to commonly asked questions.
