DC/OS 上的 HDFS 关闭端口 22。无法在任何 HDFS 节点上使用 SSH

Question

我已经在我的 10 台核心 OS 机器（3 个主节点，7 个代理节点）的 dcos 集群上安装了来自 universe 的 HDFS。我的 HA HDFS 配置有 2 个名称节点、3 个日志节点和 5 个数据节点。在 long 运行中，HDFS 所在的代理节点运行ning - 所有这些节点，无论它们是名称节点、日志节点还是数据节点 - 都关闭了它们的端口 22，所以我无法通过 ssh 进入它们，而 HDFS 未运行ning 的节点保持其端口 22 打开。关于为什么会发生或我应该寻找什么来理解为什么会发生的任何想法？

这里是集群代理节点上运行ning nmap 之后的日志。节点 13 和 16 没有 HDFS 角色，并保持其 22 端口打开。安装了 HDFS 的所有其他节点都关闭了端口 22。

Answer 1

正如我对的回答中提到的：

在 DC/OS 的 Universe HDFS 包的错误版本中发现了问题。 DC/OS 的全新 HDFS 软件包将在接下来的几周内在 Universe 上发布。
