kumachanz opened a new issue #11942:
URL: https://github.com/apache/druid/issues/11942
### Affected Version
Druid 0.22.0
### Description
We have kafka auto scaling configuration set up and working correctly.
We have 2 instances of coordinator running configured also as overlord.
When we restarted the coordinator, the kafka ingestion tasks were started
but we noticed lag started to increase over time.
Auto scaling was no longer happening and there was only one kafka task
running.
In Druid Console, checked the payload for the supervisor task and can see
`"autoscalerConfig": null`
I pushed our original supervisor task again with the following:
` "autoScalerConfig": {
"enableTaskAutoScaler": true,
"taskCountMax": 6,
"taskCountMin": 1,
"scaleOutThreshold": 10000000,
"scaleInThreshold": 500000,
"scaleInStep": 1,
"scaleOutStep": 1,
"scaleActionPeriodMillis": 1800000
}`
and it now shows in the supervisor task payload, and task scaling is
happening again.
