java-jar h2o.jarh2o.init（）如果未指定IP地址，并且h2o.init（）未找到已运行的h2o实例，则如果startH2O为true，则h2o.init（）将尝试创建一个实例。表示端口54321或端口54322不可用的消息正是这一意思。即使不是你想要的，其中一个肯定已经被拿走了。使用“netstat-anp”诊断linux上的端口使用情况。好的，我在公司的一位软件工程师那里找到了一个解决方案 他只编写了一个名为“java-jar h2o.jar”的bash，手动启动h2o集群，并在R脚本中通过
h2o.init(ip="machine_ip",port=number_port,startH2O=FALSE)

您是否尝试更改默认端口？请参阅更新的帖子。谢谢您是否尝试更改默认端口？请参阅更新的帖子。谢谢我向您保证，我做的第一件事是检查哪些端口可用，甚至在运行“java-jar h2o.jar”之前。我向您保证，我做的第一件事是检查哪些端口可用，甚至在运行“java-jar h2o.jar”之前
