cassandra - 启动简约的独立 cassandra 无法通过“cassandra -f”工作

问题描述

最新的cassandra是从网站下载的。我正在遵循https://medium.com/@areeves9/cassandras-gossip-on-os-x-single-node-installation-of-apache-cassandra-on-mac-634e6729fad6的指示

Cassandra已安装：

22:26:40/cassandra $cassandra -v
3.11.4

我开始cassandra如下：

2:23:04/cassandra $bin/cassandra -f

然而，当试图找到cassandra.config：

Exception (org.apache.cassandra.exceptions.ConfigurationException) encountered during startup: Expecting URI in variable: [cassandra.config]. Found[cassandra.yaml]. Please prefix the file with [file:///] for local files and [file://<server>/] for remote files. If you are executing this from an external tool, it needs to set Config.setClientMode(true) to avoid loading configuration.

这是目录信息：

我已确保这些conf文件在<installation_home>/conf. 未cassandra.yaml更改：它是tar.gz下载的默认内容。

为什么这根本不能开箱即用（过去启动独立的 cassandra 很容易..）？

解决方案

像这样设置系统变量：

System.setProperty("cassandra.config", "file:////cassandra.yaml");
