Allan Yang commented on HBASE-18248:
------------------------------------
I have one question, how do you define warn time for each monitored task? For
big compactions, it will last for several hours. But for tasks like opening
region , it is not normal if it lasts more than several minutes.
Another suggest is that can we reuse the toMap() method in
MonitoredRPCHandlerImpl when enriching its toString() method?

> Warn if monitored task has been tied up beyond a configurable threshold. We
> especially want to do this for RPC tasks. Use a separate threshold for
> warning about stuck RPC tasks versus other types of tasks.
