             Summary: HiveServer2 with http transport mode spending too much time just creating configs
                 Key: HIVE-14545
                 URL: https://issues.apache.org/jira/browse/HIVE-14545
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
            Reporter: Rajesh Balamohan
            Assignee: Rajesh Balamohan
            Priority: Minor


Env: Hive master with LLAP with Q-55 running via beeline mode continuously.  Query itself completes in 0.6 - 0.7 seconds. HiveServer2 is configured with  {{hive.server2.transport.mode=http}} and {{hive.server2.long.polling.timeout=1000}}
In such cases, HiverServer2 consistently runs with high CPU usage and profiling shows spending too much time just for creating hiveConf.
