Szehon Ho commented on HIVE-11903:
----------------------------------
Thanks, unfortunately I think this might be a more difficult than we
anticipated and we would need to do some research, as the number of singletons
is not going to be useful.
Can we hook into the Watcher interface to increment/decrement connection count?
There is some examples in HiveServer2.
