我正在尝试从Ambari启动一个HBase主节点。
它无法启动,因为无法连接到Zookeeper服务器。
Ambari将所有Zookeeper服务器(3个节点)标记为运行中。
运行Zookeeper服务器应用程序的应用服务器(tomcat?)似乎正常运行;至少有一个在指定端口上侦听的服务。
但是该应用程序无法连接到其他节点,似乎无法启动。
所有连接都以错误消息“ZooKeeperServer not running”关闭,客户端会显示“zookeeper.ClientCnxn: Unable to read additional data from server sessionid 0x0, likely server has closed socket”的错误信息。
这是这些节点的Zookeeper服务器日志输出(所有节点都是相同的日志,只有节点名称不同):

还有其他的问题吗?
如何解决这个问题呢?

上遇到了UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 58: ordinal not in range(128)
的问题。请问您知道我该如何解决吗? - NotGaeL
