Question

我在相关节点上运行了zookeeper守护程序，并尝试启动kafka代理，但收到以下错误：

FATAL [Kafka Server 13], Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
java.lang.NumberFormatException: For input string: "2181""

我的server.properties

broker.id=13
port=9092
host.name=node013
num.network.threads=3
num.io.threads=8
zookeeper.connect="node014:2181,node135:2181,node136:2181"
zookeeper.connection.timeout.ms=6000

和zookeeper.properties

dataDir=/tmp/zookeeper
clientPort=2181
maxClientCnxns=0

我已经尝试但未能弄清楚为什么错误日志在port属性中显示额外的“。任何想法可能导致问题？

Answer 1

在server.properties文件中，您需要删除双引号。它应该是

zookeeper.connect=node014:2181,node135:2181,node136:2181

Answer 2

可以通过删除端口“2181”和命令行选项“--list”之间的空格来解决异常。

$ ./kafka-topics --zookeeper localhost：2181 --list 线程“main”中的异常java.lang.NumberFormatException：对于输入字符串：“2181” at java.lang.NumberFormatException.forInputString（NumberFormatException.java:65）在java.lang.Integer.parseInt（Integer.java:580）在java.lang.Integer.parseInt（Integer.java:615）在org.apache.zookeeper.client.ConnectStringParser。（ConnectStringParser.java:72）在org.apache.zookeeper.ZooKeeper。（ZooKeeper.java:443）在org.apache.zookeeper.ZooKeeper。（ZooKeeper.java:380）在org.I0Itec.zkclient.ZkConnection.connect（ZkConnection.java:70）在org.I0Itec.zkclient.ZkClient.connect（ZkClient.java:1228）在org.I0Itec.zkclient.ZkClient。（ZkClient.java:157）在org.I0Itec.zkclient.ZkClient。（ZkClient.java:131） at kafka.utils.ZkUtils $ .createZkClientAndConnection（ZkUtils.scala：103） at kafka.utils.ZkUtils $ .apply（ZkUtils.scala：85） at kafka.admin.TopicCommand $ .main（TopicCommand.scala：58）在kafka.admin.TopicCommand.main（TopicCommand.scala）
