第一次启动 Cassandra 时出错
Error while starting Cassandra for first time
我第一次尝试在 Redhat 机器上启动 Cassandra。我已经在练习 Ubuntu 机器上成功地完成了，但是由于某种原因，Redhat 安装出现了以下错误：
INFO [main] 2017-06-29 20:11:42,369 YamlConfigurationLoader.java:89 - Configuration location: file:/home/cassandra/apache-cassandra-3.10/conf/cassandra.yaml

我对 yaml 所做的唯一更改是我将数据和日志文件设置如下：
data_file_directories: /var/lib/cassandra/data
commitlog_directory: /var/log/cassandra/commitlog
这是一个单节点让它工作的概念机器证明。我可以向更有经验的用户寻求帮助吗？
谢谢！
问题出在 yaml 文件上：
data_file_directories: /var/lib/cassandra/data
它需要是：
data_file_directories:
- /var/lib/cassandra/data
