Hmm, that is strange. I would expect an ERROR in the KafkaInputOperator
around 21:01. Please check the earliest killed container log.

Brandon,
Is the stacktrace from the app master log or is it from a local mode
run? The exception is raised due to the buffer server termination in
one of the operators containers and I guess that it happens when app
master tries to purge data from the buffer server. Check the operators
containers logs for exceptions/errors unless the application was
started in the local mode. In the later case, try to enable DEBUG level.
Thank you,
Vlad

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:
