zookeeper-NIOServerCnxn @ 383]-导致会话0x0关闭的异常：Len错误1195725856

时间：2019-04-18 18:27:37

标签： apache-zookeeper java-11

我正在尝试在Windows中安装Zookeeper。无论我在zookeeper + Kafka - Unable to create data directory中遵循哪个建议，我都会遇到以下错误提示。

我以管理员身份运行它，并且尝试了所有这些选项：

#dataDir=/tmp/zookeeper
#dataDir=:\zookeeper-3.4.14\
#dataDir=C:\\_d\\WSs\\kafka\\zookeeper-3.4.14\\data
#dataDir=:\\\\zookeeper\\\\data
dataDir=C:\\_d\\WSs\\kafka\\zookeeper-3.4.14

我认为这无关紧要，但让我在这里添加：我有Java 11。

任何知道为什么会发生的想法都会受到赞赏。

***我的问题的答案是“您可以忽略在curl 127.0.0.1:port时出现错误的事实。Kafka仍在工作。

1 个答案:

答案 0 :(得分：2)

您是否要对Zookeeper客户端端口执行“ HTTP GET”操作？

因此错误来自 NIOServerCnxn.java:readLength ，它期望使用4个字母的命令或缓冲区，其中前4个字节代表大小。

十六进制数字1195725856为0x47455420，以ASCII表示为“ GET”。

因此，当您尝试对2181端口执行HTTP GET时，会导致错误消息。

  $ curl http://0.0.0.0:2181/
curl：（52）来自服务器的空回复
$ sudo tail /var/log/zookeeper/zookeeper.out

可以安全地忽略此 WARN 消息，因为ZooKeeper只会关闭 curl 响应所隐含的客户端会话。
