java.lang.ClassNotFoundException when trying to run camus

Question

I downloaded the confluent package which includes camus jars and I followed the instructions online enter link description here.

Hadoop is properly setup (meaning I can use hadoop fs -ls commands and other hadoop jar commands). However, when i tried to run

hadoop jar confluent-camus-1.0.jar com.linkedin.camus.etl.kafka.CamusJob

I got "main" classNotFound error

Exception in thread "main" java.lang.ClassNotFoundException: com.linkedin.camus.

        at org.apache.hadoop.util.RunJar.main(RunJar.java:205)

The the path to the "confluent-camus-1.0.jar" is correct (right under the folder). I didn't start the kafka service, just to try to run it.

Anyone got similar problems?

Thanks.

Maybe you miss some jars inn your classpath? – Jakub Apr 16 '15 at 21:41 — Jakub, Apr 16 '15 at 21:41

You should try to inspect your jar file:

jar tvf confluent-camus-1.0.jar | grep com.linkedin.camus.etl.kafka.CamusJob

If you do not find this class, try to find it in other jar, which generated by camus.

After you should add target jar with

hadoop jar confluent-camus-1.0.jar com.linkedin.camus.etl.kafka.CamusJob -libjars {JAR_NAME}
