Andrew Purtell updated HBASE-4349:
----------------------------------
Description:
Would be nice to add some metrics for each of the monitored tasks and executor
services in the master and region server:
- number of items in the queue
- age of the oldest yet-unprocessed item (ie in the queue or currently being
handled)
- number of threads in the executor currently busy
These would allow us to monitor better for cases where things get "stuck"
