> 1. One rs died, the servershutdownhandler found it out and started the distributed log
splitting;
> 2. All tasks are failed due to ZK connection lost, so the all the tasks were deleted
asynchronously;
> 3. Servershutdownhandler retried the log splitting;
> 4. The asynchronously deletion in step 2 finally happened for new task
> 5. This made the SplitLogManger in hanging state.
> This leads to .META. region not assigened for long time
