From your screenshot it looks like you are using kafka in a kerberozed environment so can you please check if youa re able to get a valid kerberos ticket?

# kinit -kt /etc/security/keytabs/kafka.service.keytab  kafka/something@EXAMPLE.COM
# klist

Also please try running the producer again after setting the following properties?

# export 
KAFKA_CLIENT_KERBEROS_PARAMS="-Djava.security.auth.login.config=/usr/hdp/current/kafka-broker/config/kafka_client_jaas.conf"

.

Additionally check if the following is set properly ? https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.2/bk_storm-user-guide/content/stormkafka-secu...

spoutConfig.securityProtocol=PLAINTEXTSASL

.

Thanks for the quick solution... it worked for me, but did not try the Strom kafka spout configuration.

@Sanjib Behera

Good to know that previously mentioned suggestion worked.

Regarding the "spoutConfig.securityProtoco" config you can refer to the following link to know more about it. Sometimes an incorrect value to this property causes issue, but in your case looks like it is alredy running fine.

Hhaving another issue while executing kafka consumer

[#7]

Currently i am getting "No brokers found in ZK." issue for the following command

"kafka-console-consumer.sh --zookeeper abc00691239901.cde.com:6667 --topic test --from-beginning"

[#8]

@Sanjib Behera Is this the same issue as provided in screenshot ? If yes, Could you please check "listeners" section in server.properties. As you are not using kerberos while consuming value of "listeners" should contain PLAINTEXT.

If this is a different error then please provide complete traceback message.

@Sanjib Behera

if the cluster is Kerberos enabled then we need "kafka-console-consumer.sh --zookeeper abc00691239901.cde.com:6667 --topic test --from-beginning --security-protocol PLAINTEXTSASL" and for Storm spout you need to have jaas file to be configured.
