Hello, I'm upgrading a topology from storm version 0.10.0 to 1.0.1 to deploy it on new HDP 2.5. The topology have a kafka spout and several bolts (hdfs, hive, hbase, socket...). Some tipical operations, as kafka spout, are packaging in separated library (called "Common") and so also this library is been updated with latest version of hadoop components. I have an issue when deploy topology, this error appears (by Storm UI) on spout: java.lang.NoClassDefFoundError: Could not initialize class org.apache.log4j.Log4jLoggerFactory at org.apache.log4j.Logger.getLogger(Logger.java:39) at kafka.utils.Logging$class.logger(Logging.scala:24) at kafka.consumer.SimpleConsumer.logger$lzycompute(SimpleConsumer.scala:35) at kafka.consumer.SimpleConsumer.logger(SimpleConsumer.scala:35) at kafka.utils.Logging$class.info(Logging.scala:75) at kafka.consumer.SimpleConsumer.info(SimpleConsumer.scala:35) at kafka.consumer.SimpleConsumer.liftedTree1$1(SimpleConsumer.scala:94) at kafka.consumer.SimpleConsumer.kafka$consumer$SimpleConsumer$$sendRequest(SimpleConsumer.scala:83) at kafka.consumer.SimpleConsumer.getOffsetsBefore(SimpleConsumer.scala:149) at kafka.javaapi.consumer.SimpleConsumer.getOffsetsBefore(SimpleConsumer.scala:79) at org.apache.storm.kafka.KafkaUtils.getOffset(KafkaUtils.java:75) at org.apache.storm.kafka.KafkaUtils.getOffset(KafkaUtils.java:65) at org.apache.storm.kafka.PartitionManager.<init>(PartitionManager.java:94) at org.apache.storm.kafka.ZkCoordinator.refresh(ZkCoordinator.java:98) at org.apache.storm.kafka.ZkCoordinator.getMyManagedPartitions(ZkCoordinator.java:69) at org.apache.storm.kafka.KafkaSpout.nextTuple(KafkaSpout.java:129) at org.apache.storm.daemon.executor$fn__6503$fn__6518$fn__6549.invoke(executor.clj:651) at org.apache.storm.util$async_loop$fn__554.invoke(util.clj:484) at clojure.lang.AFn.run(AFn.java:22) at java.lang.Thread.run(Thread.java:745) Searching the error, I see that is necessary exclude log4j in pom.xml but the results is the same. I have also try to use old library of kafka but nothing is changed.

Could you have any suggestion to solve it? Thanks in advance, Giuseppe ... View more

Hi All, We have upgraded our environment from HDP 2.3.4 to HDP 2.4 and so review Storm topologies in order to use 1.0.1 version and new features. In old version, storm-kafka library (0.9.2) included the option "forceFromStart" in SpoutConfig that restore data from beginning (if set to true) or get only current value (if set to false) by kafka. In last version the option is removed and I see that the spout get always data from beginning. How we can replace the functionality in new version? I mean, I want get only the current value from spout, how I can proceed to do it? Thanks in advance, Giuseppe ... View more
