Hello,

I am trying to connect Cygnus to Kafka

I am connected to the zookeeper but no values have been persisted in Kafka and I got this exception:

time=2016-02-24T11:48:24.197UTC | lvl=WARN | trans= | srv= | subsrv= | function=poll | comp=Cygnus | msg=org.apache.kafka.common.network.Selector[276] : Error in I/O with host myKafkaHostName/ myKafkaHostIP

java.io.EOFException

at org.apache.kafka.common.network.NetworkReceive.readFrom(NetworkReceive.java:62)

at org.apache.kafka.common.network.Selector.poll(Selector.java:248)

at org.apache.kafka.clients.NetworkClient.poll(NetworkClient.java:192)

at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:122)

at java.lang.Thread.run(Thread.java:745)

Any idea what is the cause?

Thanks & Best regards,

Hi again Sabrine,

I will need the complete log trace and the configuration you are using.

Hi,

I¹m afraid I cannot do nothing. It seems an open problem about Kafka:

https://issues.apache.org/jira/browse/KAFKA-2078

I¹ve seen 160 notifications where successfully persisted before that. Is
that true? I mean, were you able to see the data before raising the
warning?

Regards,
Francisco

Hi,

Please find log file and kafka agent configuration in the attached files.

For your information, I tested with another kafka instance and the result
is the following:
Even after the warning appearance, the kafka instance is able of
receiving new data.
But still I am interested in knowing the warning cause.
Thanks!
