Additionally the "host_in_memory_aggregation" value is actually getting populated from "ams-site" as following:

# grep 'timeline.metrics.host.inmemory.aggregation' /var/lib/ambari-server/resources/common-services/KAFKA//0.8.1/package/scripts/params.py
host_in_memory_aggregation = str(default("/configurations/ams-site/timeline.metrics.host.inmemory.aggregation", True)).lower()

.

Hence please check your "ams-site" config in ambati UI to see if it has correct boolean values (true / false)?

Ambari UI --> Ambari Metrics --> Configs --> Advanced --> Advanced ams-site --> "Enable in-memory aggreation on monitors" Property

Correct the above property value and then restrat AMS service followed by Kafka restart and then you should no longer see the mentioned error.
