zookeeper服务器没有运行

标签： hbase apache-zookeeper ambari

我正试图从ambari开始一个hbase大师。

无法启动它，因为它无法连接到zookeper服务器。

Ambari将所有zookeper服务器（3个节点）标记为正在运行。

运行zookeper服务器应用程序的应用程序服务器（tomcat？）似乎运行正常;至少有一个服务侦听指定的端口。

但是应用程序无法连接到其他节点，似乎它无法启动。

关闭所有连接，并在zookeeper服务器日志上显示错误消息docker start，在客户端上显示ZooKeeperServer not running。

这是这些节点的zookeper服务器日志输出（所有节点的日志相同，只有节点名称更改）：

zookeeper.ClientCnxn: Unable to read additional data from server sessionid 0x0, likely server has closed socket

当客户端尝试连接时：

有关如何解决此问题的任何想法？

您的选举端口正在sgX.imatiasl.lan/127.0.0.1:3888绑定所有节点，因此当客户端尝试连接到sgY.imatiasl.lan/10.7.0.93:3888时，它会失败。

选举端口应绑定到0.0.0.0:3888或每个节点的真实IP，但由于某种原因，它们将被解析为127.0.0.1。您可以使用netstat -patun检查每个节点中的IP：端口以确认这一点。

很可能你在/etc/hosts时遇到了一些问题。 看看：https://unix.stackexchange.com/questions/240506/zookeeper-dns-name-problems-with-leader-elections-when-migrating-from-windows-to

尝试执行＆＃34; jps＆＃34;您的节点上的命令，看看zookeeper服务是否已启动， 如果没有启动它。
