       Is it possible to have my mapper in Perl and reducer in java. In my existing legacy
system some larger process is being handled by Perl and the business logic of those are really
complex. It is a herculean task to convert all the Perl  to java. But the reducer business
logic which is again pretty complex is handled by the existing system in JAVA. Now I need
to design map reduce reusing the existing code.  Has anyone already implemented some use cases
in the same direction? If so please share the details.

Thank You
