> HiveServer2: Provide the user with different error messages depending on the

> Key: HIVE-9423
> URL: https://issues.apache.org/jira/browse/HIVE-9423
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 0.12.0, 0.13.0, 0.14.0, 0.15.0
> Reporter: Vaibhav Gumashta
> Assignee: Peter Vary
> Attachments: HIVE-9423.2.patch, HIVE-9423.3.patch, HIVE-9423.4.patch,

>
> An example of where it is needed: it has been reported that when # of client
> connections is greater than {{hive.server2.thrift.max.worker.threads}},
> HiveServer2 stops accepting new connections and ends up having to be
> restarted. This should be handled more gracefully by the server and the JDBC
> driver, so that the end user gets aware of the problem and can take
> appropriate steps (either close existing connections or bump of the config
> value or use multiple server instances with dynamic service discovery
> enabled). Similarly, we should also review the behaviour of background thread
> pool to have a well defined behavior on the the pool getting exhausted.
> Ideally implementing some form of general admission control will be a better
> solution, so that we do not accept new work unless sufficient resources are
> available and display graceful degradation under overload.
