Hi guys,
We are using Flink 1.0-SNAPSHOT with Kafka 0.9 Consumer and we have not
been able to retrieve data from our Kafka Cluster. The DEBUG data reports
the following:
10:53:24,365 DEBUG org.apache.kafka.clients.NetworkClient

sendTimeMs=1455702804398),
responseBody={error_code=15,coordinator={node_id=-1,host=,port=-1}})
We receive this message all the time. What we don't know understand is this
"responseBody={error_code=15,coordinator={node_id=-1,host=,port=-1}}", as
we see an error_code we suppose there was a problem. Our Kafka cluster
works and we have some clients extracting data from it, so we don't know if
this could be a Kafka issue or a Flink issue.
Does anyone know, or understand, this response we are getting from Kafka?
Thanks.
