Hi, Hadoop experts,
I've written my custom GroupComparator, and I want to tell Hadoop about it.
Now, there is a call
but I only find it in mapreduce package of version 0.21. In prior versions,
I see a similar call
but it does not cause my GroupComparator to be being used.
So my question is, should I change the code to use the mapreduce package
(not a problem, since Cloudera has it backported to the current
distribution), or is there a different, simpler way?
Thank you. Sincerely,
