There is a tableInputFormat class in org.apache.hadoop.hbase.mapreduce.TableInputFormat
Also, if you want to use TableMapReduceUtil you probably want to have your mapper function extend TableMapper. Check out the javadocs for more info: http://hadoop.apache.org/hbase/docs/current/api/index.html -----Original Message----- From: Something Something [mailto:luckyguy2...@yahoo.com] Sent: Thursday, October 15, 2009 1:37 AM To: gene...@hadoop.apache.org; hbase-user@hadoop.apache.org Subject: Re: Question about MapReduce If the answer is...

I would like to pass 3 arguments to the Mapper & Reducer to work on. Basically, these arguments are keys on the 3 different tables on HBase. In other words, I don't want to use FileInputFormat or DbInputFormat because everything I need is already on HBase. How can I do this? Please let me know. Thanks.
