abk-code opened a new issue #10217:
URL: https://github.com/apache/druid/issues/10217
Context: Recently did a rolling upgrade from 0.17 to 0.19 (skipped 0.18.x)
and using spark/EC2 based streaming using avro via Kafka. Kafka indexer jobs
are running with the specfiles (supervisor). These are tested specfiles that
have run for long time on 0.17. But seeing the following error.

I've multiple supervisors (for different datasources) and many tasks are
failing with similar error.
