Dear experts,I am running HDP 2.6.4 with enabled Kerberos and Ranger.Because the default zookeeper path of Kafka is under the root directory /, in order to facilitate the management of Kafka, the storage path of Kafka was changed to /kafka on the ambari page. After change,the zookeeper.connect is:       hdp-node1:2181,hdp-node2:2181,hdp-node3:2181/kafka       Now I have a problem. When I create a topic with the following command, the following exception appears       sh kafka-topics.sh --create --zookeeper hdp-node1:2181,hdp-node2:2181,hdp-node3:2181/kafka --replication-factor 1 --partitions 3 --topic test_topic       And the follwing ERROR:       ERROR org.I0Itec.zkclient.exception.ZkException: org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /config/topics at org.I0Itec.zkclient.exception.ZkException.create(ZkException.java:68) at org.I0Itec.zkclient.ZkClient.retryUntilConnected(ZkClient.java:1000) at org.I0Itec.zkclient.ZkClient.create(ZkClient.java:527) at org.I0Itec.zkclient.ZkClient.createPersistent(ZkClient.java:293) at kafka.utils.ZkPath$.createPersistent(ZkUtils.scala:965) at kafka.utils.ZkUtils.createParentPath(ZkUtils.scala:437) at kafka.utils.ZkUtils.updatePersistentPath(ZkUtils.scala:507) at kafka.admin.AdminUtils$.writeEntityConfig(AdminUtils.scala:568) at kafka.admin.AdminUtils$.createOrUpdateTopicPartitionAssignmentPathInZK(AdminUtils.scala:453) at kafka.admin.AdminUtils$.createTopic(AdminUtils.scala:415) at kafka.admin.TopicCommand$.createTopic(TopicCommand.scala:107) at kafka.admin.TopicCommand$.main(TopicCommand.scala:60) at kafka.admin.TopicCommand.main(TopicCommand.scala) Caused by: org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /config/topics at org.apache.zookeeper.KeeperException.create(KeeperException.java:113) at org.apache.zookeeper.KeeperException.create(KeeperException.java:51) at org.apache.zookeeper.ZooKeeper.create(ZooKeeper.java:783) at org.I0Itec.zkclient.ZkConnection.create(ZkConnection.java:99) at org.I0Itec.zkclient.ZkClient$3.call(ZkClient.java:530) at org.I0Itec.zkclient.ZkClient$3.call(ZkClient.java:527) at org.I0Itec.zkclient.ZkClient.retryUntilConnected(ZkClient.java:990) ... 11 more         Please help me to solve this ERROR,I should create topic in kafka normally. ...
