使用Kafka Shell命令无法操作Kafka集群
问题背景与现象
用户执行Kafka命令查看当前topic信息，但发现业务执行失败。
具体信息如下：
root@Slave2bin]#./kafka-topics.sh --describe --topic example-metric1 --zookeeper 192.119.147.231:2181,192.119.147.228:2181,192.119.147.227:2181 Error while executing topic command:org.apache.zookeeper.KeeperException$AuthFailedException:KeeperErrorCode=AuthFailedfor/brokers/topics [2016-09-2616:58:59,873]ERRORorg.I0Itec.zkclient.exception.ZkException:org.apache.zookeeper.KeeperException$AuthFailedException:KeeperErrorCode=AuthFailedfor/brokers/topics atorg.I0Itec.zkclient.exception.ZkException.create(ZkException.java:68) atorg.I0Itec.zkclient.ZkClient.retryUntilConnected(ZkClient.java:995) atorg.I0Itec.zkclient.ZkClient.getChildren(ZkClient.java:675) atorg.I0Itec.zkclient.ZkClient.getChildren(ZkClient.java:671) atkafka.utils.ZkUtils.getChildrenParentMayNotExist(ZkUtils.scala:548) atkafka.utils.ZkUtils.getAllTopics(ZkUtils.scala:798) atkafka.admin.TopicCommand$.getTopics(TopicCommand.scala:82) atkafka.admin.TopicCommand$.describeTopic(TopicCommand.scala:183) atkafka.admin.TopicCommand$.main(TopicCommand.scala:66) atkafka.admin.TopicCommand.main(TopicCommand.scala) Causedby:org.apache.zookeeper.KeeperException$AuthFailedException:KeeperErrorCode=AuthFailedfor/brokers/topics atorg.apache.zookeeper.KeeperException.create(KeeperException.java:127) atorg.apache.zookeeper.KeeperException.create(KeeperException.java:51) atorg.apache.zookeeper.ZooKeeper.getChildren(ZooKeeper.java:2256) atorg.apache.zookeeper.ZooKeeper.getChildren(ZooKeeper.java:2284) atorg.I0Itec.zkclient.ZkConnection.getChildren(ZkConnection.java:114) atorg.I0Itec.zkclient.ZkClient$4.call(ZkClient.java:678) atorg.I0Itec.zkclient.ZkClient$4.call(ZkClient.java:675) atorg.I0Itec.zkclient.ZkClient.retryUntilConnected(ZkClient.java:985) ...8more (kafka.admin.TopicCommand$)
原因分析
用户反馈已经排查了执行此命令的账号权限，此账号具有操作Kafka组件的最高权限，不应该仍然会有权限不足的问题。
经确认执行命令有问题，访问ZooKeeper上所存放的Kafka信息，其路径（Znode）应该加上/kafka，完整的查询命令应该是：
root@Slave2bin]#./kafka-topics.sh --describe --topic example-metric1 --zookeeper 192.168.147.231:2181,192.168.147.228:2181,192.168.147.227:2181/kafka
解决办法
属于命令操作有误，具体细节请参考Kafka Shell命令章节。
