--------------------------------------
Summary: HiveServer2: handle max handler thread exhaustion
gracefully
Key: HIVE-9423
URL: https://issues.apache.org/jira/browse/HIVE-9423
Project: Hive
Issue Type: Bug
Components: HiveServer2
Affects Versions: 0.15.0
Reporter: Vaibhav Gumashta
It has been reported that when # of active client connections is greater than
{{hive.server2.thrift.max.worker.threads}}, HiveServer2 becomes unresponsive.
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).
