MultiTableInputFormat to compare 2 tables taking about 80 mins

Hi,

I am using Hbase MultiTableInputFormat to compare 2 tables: Table1 (7
million), Table2 (30 million).

In the driver, i am passing to scans ( without any filters). In my mapper i
am doing a compare and writing the summary in Reducer.

Any settings specific to this scenario that might speed up the process.
Thanks.
