--------------------------------
The patch LGTM ... will let [~vgumashta]/[~thejas] give the official nod.
> HiveServer2 with http transport mode spends too much time just creating
> configs

> 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.
