---------------------------------------
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.
