Hi,
I’m trying to launch my first Kafka indexing service with imply 2.9.6.
When I started the druid it failed to start because of caffeine-cache wasn’t installed so remove it from the comm props.
Moreover, the router service failed to start so I comment it out, I don’t need the router for now.
The Druid launched successfully 
I sent indexing service task with bellow configuration, and most of my tasks failed 
attached log of one of my failed tasks.
Do you have any idea why it failed?
thx
