> 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.
