Description
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.
