> Project: Hive
> Issue Type: Sub-task
> Components: HiveServer2
> Reporter: Siddharth Seth
> Priority: Critical
>
> 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
