Subject: new join algorithm using mapreduce
To: [EMAIL PROTECTED]
I am writing new join algorithm using hadoop
and want to do multi way join in single mapreduce job
map --> processes all dataset
reduce-->  join of all dataset
                + aggregate operation

second mapreduce job

will collect result from multple reducer files of first job

I am pretty clear about map phase but dnt have idea how to process
all dataset in single reduce.

So how i should proceed and
do i need to modify code of mapreduce
Thanks
