> 841 instances of HiveConf.
> 831 instances of UDFClassLoader
> This is on a HS2 instance configured to run 10 concurrent queries with LLAP.
> 10 SessionState instances. Something is holding on to the additional HiveConf, UDFClassLoaders
- potentially HMSHandler.
> This is with an embedded metastore.
