Fwd: cost model for MR programs
bharath vissapragada 2009-08-25, 03:01
Hi all ,

Is there any general cost model that can be used to guess the run time of a
Map reduce program (similar to Page IO/s , selectivity factors in RDBMS) in
terms of any config aspects such as number of nodes/page IO/s etc .

Thanks .
