Mariappan Asokan updated MAPREDUCE-4812:
----------------------------------------
Attachment: mapreduce-4812.patch
Hi Arun & Alejandro,
I am uploading a patch that implements the bare-bones requirements for the
reduce input merger plugin. I will create a simple mock test for the plugin
and post it with some protection changes so that the test will run.
Arun, in this patch an instance of {{ReduceInputMerger}} plugin is passed to
{{Shuffle}} constructor as you asked for. I figured out a way to implement
sort avoidance plugin. However, I need MAPREDUCE-4049(shuffle plugin) to be
committed before that.
Thanks.
