Subject: new join algorithm using mapreduce
To: user@hadoop.apache.org
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
