Linking 2 MarReduce jobs together?

Is it possible to put the output from the reduce phase of job 1
to be the input to job number 2, or is the best way to write it
to a HBase table  or to the HDFS and the fetch it in the second job?

Erik,

Well your data has to be somewhere between the two jobs... So I'd say yes,
put it in HBase or HDFS to reuse it (or maybe I didn't understand your
question).

Regards,
