Hi Bharath! Yeah, that is what Jonathan means. If you need data from 2 tables in your mapper, you can have one as the standard input and in your mapper make explicit calls to HBase and request data from it into your mapper, just like you did in your example.
Yes, you can output as many pairs as you want from every mapper, it doesn't have to be a one to one ratio. Not really sure what you want to do with your data, do you want to compute some output using data from the two tables or simple do the same thing for both tables? Regards Erik
