Subject Connection refused exception
Date Tue, 29 Nov 2016 13:54:20 GMT
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:
