Sorry as I am new to Kafka/ZK, but the instruction seems not clear.. In the config, it was said that we can use a chroot-ed ZK ( http://kafka.apache.org/configuration.html), e.g. localhost:2181/kafka
But when I start the Kafka using the setting, it was showing.. java.lang.IllegalArgumentException: Path length must be > 0 at org.apache.zookeeper.common.PathUtils.validatePath(PathUtils.java:48) at org.apache.zookeeper.common.PathUtils.validatePath(PathUtils.java:35) at org.apache.zookeeper.ZooKeeper.create(ZooKeeper.java:626) at org.I0Itec.zkclient.ZkConnection.create(ZkConnection.java:87) at org.I0Itec.zkclient.ZkClient$1.call(ZkClient.java:308) at org.I0Itec.zkclient.ZkClient$1.call(ZkClient.java:304) at org.I0Itec.zkclient.ZkClient.retryUntilConnected(ZkClient.java:675) at org.I0Itec.zkclient.ZkClient.create(ZkClient.java:304) at org.I0Itec.zkclient.ZkClient.createPersistent(ZkClient.java:213) at org.I0Itec.zkclient.ZkClient.createPersistent(ZkClient.java:223) at org.I0Itec.zkclient.ZkClient.createPersistent(ZkClient.java:223) at kafka.utils.ZkUtils$.createParentPath(ZkUtils.scala:47) at kafka.utils.ZkUtils$.createEphemeralPath(ZkUtils.scala:59) at kafka.utils.ZkUtils$.createEphemeralPathExpectConflict(ZkUtils.scala:71) at kafka.server.KafkaZooKeeper.registerBrokerInZk(KafkaZooKeeper.scala:54) at kafka.log.LogManager.startup(LogManager.scala:130) at kafka.server.KafkaServer.startup(KafkaServer.scala:81) at kafka.server.KafkaServerStartable.startup(KafkaServerStartable.scala:34) at kafka.Kafka$.main(Kafka.scala:47) at kafka.Kafka.main(Kafka.scala) In an old post ( http://mail-archives.apache.org/mod_mbox/incubator-kafka-users/201205.mbox/%3CCAK152briB=m-oaeaqtcz+cvzjovywbhomx8tubywqguox_y...@mail.gmail.com%3E) it was saying I need to create the path first, so I use zkCli.sh to connect to the ZK, and run the command >> create /kafka '' I restarted the Kafka and still the same error, any idea? Thanks.
