Hi We're using Hive 2.3.1, we recently migrated our production amazon EC2 instance types from r5.24xlarge to r6i.32xlarge
on the r6 instance we have seen steady cpu usage growth that can all be attributed to our org.apache.hive.service.server.HiveServer2 Even when this change is unreleased and this process is going effectively unused the CPU usage grows slowly until we restart that process In the attached graph you can see that CPU usage grows until we restart HiveServer2 after that it remains stable for a while and then usage starts growing on HiveServer2 . After we restarted that process we failed back to our previous server (leaving this server unused) but the CPU usage on HiveServer2 on this server continue to grow [cid:image001.png@01D8C129.E33179C0] We've since built instances in dev with both r5 and r6i and all the r6i instances have the above problem and all the r5 do not..... Does anyone have any idea why this might be? ---------------------------------------------------------------------- This email and any attachment is confidential.
