This pops up a little while later. I’ll have to check to see if I can see
anything before!

Subject: Re: Connection refused exception
Brandon,
This is not related to kafkaInputOperator talking to Kafka. Do you see any
other exceptions in the logs around this exception before or after?

Hello,
I’m wondering if anyone has seen a similar stack trace before as there isn’t a
lot of info provided. I’m wondering if the connection refused is from one
operator to another or the kafkaInputOperator being unable to connect to kafka.
Any ideas? Here’s the stacktrace:
