> We are seeing one drillbit creates hundreds of connections to hive meta
> store. This indicates that drill is leaking those connection, and did not
> close those connections properly. When such leaking happens, it may prevent
> other applications from connecting to hive meta store.
> It seems one cause of leaking connection happens when hive meta store client
> call hits exception.
