---------------------------------------

             Summary: Better resource management in HiveServer2
                 Key: HIVE-10725
                 URL: https://issues.apache.org/jira/browse/HIVE-10725
             Project: Hive
          Issue Type: Bug
            Reporter: Vaibhav Gumashta
            Assignee: Vaibhav Gumashta


We have various ways to control the number of queries that can be run on one HS2 instance
(max threads, thread pool queuing etc). We also have ways to run multiple HS2 instances using
dynamic service discovery. We should do a better job at:
1. Monitoring resource utilization (sessions, ophandles, memory, threads etc).
2. Being upfront to the client when we cannot accept new queries.
3. Throttle among different server instances in case dynamic service discovery is used.
4. Consolidate existing ways to control #queries into a simpler model.
