【问题描述】:
我正在尝试使用 dcos package install cassandra 在 Mesos 上安装 Cassandra,但收到以下错误消息:
The Apache Cassandra DCOS Service implementation is alpha and there may be bugs, incomplete features, incorrect documentation or other discrepancies.
The default configuration requires 3 nodes each with 0.3 CPU shares, 1184MB of memory and 272MB of disk.
Continue installing? [yes/no] yes
Installing Marathon app for package [cassandra] version [0.2.0-1]
URL [http://localhost/marathon/v2/info] is unreachable: HTTPConnectionPool(host='localhost', port=80): Max retries exceeded with url: /marathon/v2/info (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x31aea10>: Failed to establish a new connection: [Errno 111] Connection refused',))
谁能解释一下为什么以及如何解决它?

这意味着您的 Marathon 框架在 localhost:80 上无法访问。你确定它真的在运行吗?
