Subject Collecting error messages from Mappers
Date Mon, 08 Oct 2012 14:13:44 GMT

Is there a simple way for error output / debug information generated by
a Mapper to be collected in one place for a given M/R job run? I guess
what I'm hoping for is sort of the reverse of a Distributed Cache function.

Can anyone suggest an approach?
