Subject [jira] [Created] (HIVE-9423) HiveServer2: handle max handler thread exhaustion gracefully
Date Tue, 20 Jan 2015 21:12:34 GMT
Vaibhav Gumashta created HIVE-9423:
--------------------------------------

             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).
