Chris Li updated HADOOP-10279:
------------------------------
Attachment: subtask2_add_mux.patch
Depends on subtask1: This multiplexer enables takers of the FairCallQueue to
withdraw in a weighted round-robin fashion to combat starvation of low-priority
Schedulables.
Weights are configurable as follows:
ipc.8020.wrr-multiplexer.weights = 30, 20, 5
Means queue0 will be drawn from thirty times, queue1 twenty times, queue2 five
times, and repeat.
> Create multiplexer, a requirement for the fair queue
