Aihua Xu commented on HIVE-14227:
---------------------------------
I think this is more like keeping track of the active operations for the
session, not the number of connections. We only call cerateContext() when the
new connection is created, not ExecuteStatement() or getCatalog(), etc.
Counting active operations may also not work since even if the count is 0, the
user may want to keep the session open and submit additional operations.
> Investigate invalid SessionHandle and invalid OperationHandle
