Yes, you can try this command to determine whether kafka-client-{version}.jar
can be found.
find -L $KAFKA_HOME -name 'kafka-clients-[a-z0-9A-Z\.-]*.jar' ! -name '*doc*' !
-name '*test*' ! -name '*sources*' ''-printf '%p:' | sed 's/:$//'
And also check check if kafka-client-{version}.jar is loaded by kylin.
cat ${KYLIN_HOME}/pid #get kylin proess id
ps -ef | grep ${pid}
Then take a look if the kafka-client.jar is included in the jars which are
loaded by kylin when kylin start.

主题: Re: When build streaming cube in kylin, I got an error tip.
Hi：
Is Kafka home set before kylin is started？If not, you can set KAFKA_HOME and
restart kylin.
If you still encounter this problem after setting KAFKA_HOME, and your hadoop
environment is hdp3.0, you can take a look at this issue
https://issues.apache.org/jira/browse/KYLIN-3970. I'm not sure if it will help
you.

Hello，dear kyliners:
Lately, We tried to create a streaming model in kylin ,which refer to
doc "Cubing from Kafka(Near RT Streaming)" in kylin official website,
and we created the model and cube successfully, but when build the cube, it
appeared an error,like this:
"
ERROR [http-nio-7070-exec-9] controller.CubeController:398 :
org.apache.kafka.clients.consumer.ConsumerConfig.configNames()Ljava/util/Set;
java.lang.NoSuchMethodError:
org.apache.kafka.clients.consumer.ConsumerConfig.configNames()Ljava/util/Set;"
<[email protected]>
our environment: kylin 2.6.3; kafka 2.0.0.
If you know where is the problem or you know how to solve it, please contact
me, thank you very much!
