--------------------------------------------------------
Attach patch v2. Fixed one additional bug in KafkaController.
The bug is that Map(("a",0)->0,("a",1)->0)).map(_,_1) returns Map("a" -> 1)
while we expect it to be Seq(("a,0),("a",1)). Fixed it by using .keySet
instead.
With patch v2, our system test now passes.
