Worker's early failure will cause the whole system fail

When there's early failure happens to a worker, the whole system will fail.

Observed failed worker:
State: Creating RPC threads failed
Result: It will cause the worker fail, however, master has already recorded and reserved these splits to this worker (identified by InetAddress), thus although hadoop reschedule a mapper for this worker, the master still waiting for the old worker's response, finally, the master will fail.
