Hi I am trying to upgrade a single node kafka broker to latest 1.0 from 0.10.
The steps followed 1. Stopped Kafka Broker 2. Replaced bin/, libs & site-docs/ with the latest 3. Started Kafka But I am seeing the below exception in logs - Anyone any thoughts? How can I get around this? 017-11-29 16:21:36.591 [main-EventThread] ClientCnxn [INFO] EventThread shut down Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/kafka/common/errors/TopicExistsException at org.apache.samza.system.kafka.KafkaSystemAdmin$$anonfun$createStream$2.apply(KafkaSystemAdmin.scala:442) at org.apache.samza.system.kafka.KafkaSystemAdmin$$anonfun$createStream$2.apply(KafkaSystemAdmin.scala:440) at org.apache.samza.util.ExponentialSleepStrategy.run(ExponentialSleepStrategy.scala:81) at org.apache.samza.system.kafka.KafkaSystemAdmin.createStream(KafkaSystemAdmin.scala:422) at org.apache.samza.system.kafka.KafkaSystemAdmin.createCoordinatorStream(KafkaSystemAdmin.scala:337) at org.apache.samza.job.JobRunner.run(JobRunner.scala:88) at org.apache.samza.job.JobRunner$.doOperation(JobRunner.scala:52) at org.apache.samza.job.JobRunner$.main(JobRunner.scala:47) at org.apache.samza.job.JobRunner.main(JobRunner.scala) Caused by: java.lang.ClassNotFoundException: org.apache.kafka.common.errors.TopicExistsException at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 9 more
