Subject Discard message LeaderSessionMessage(null,ConnectionTimeout)
Date Tue, 13 Sep 2016 15:10:50 GMT

while running a job on Flink 1.1.2 on a cluster of 3 nodes using the
KafkaProducer010, I encounter this error:

WARN  org.apache.flink.runtime.client.JobClientActor                -
Discard message LeaderSessionMessage(null,ConnectionTimeout) because the
expected leader session ID 4a1c16fe-d015-4351-81ea-814796e2167f did not
equal the received leader session ID null.

The KafkaProducer010 works locally but on the cluster fails to read from
the topic. I can correctly read and write using console producer and
consumer so I don't think it's misconfigured.

I would like to know what could be the cause of the error, if it is related
to the issue I'm facing on the flink-kafka connector and maybe if it's due
to the upgrade to the version 0.10. I know the producer is still in a PR
but it showed to work properly in a local environment.

Thank you,
