> Using -Dgiraph.SplitMasterWorker=false with a recent trunk (r1401165) caused the machine who is playing the master role (showing itself as {{ALL}} from the task tracker page) to throw ClassCastException (SendVertexRequest -> MasterRequest) from MasterRequestServerHandler class.  I'm trying to use as many machines as possible for actual computation (can't afford to waste one for master+ZK).  This worked fine with r1388628 (roughly a month ago), so a recent change must've broken something.  Here's the relevant log I captured:
