Subject mapside joins
Date Wed, 21 Jul 2010 14:04:03 GMT



Hi

Does join only work with text like files ?

Is it possible to do map-side join using custom Writable. Say I have
writables, custom1 and custom2 and there is one common field (say id)
that could join the records in these 2 objects.

So will it be possible to join these 2 files and output writable
custom3 ?

thanks
