### 集群变化(Cluster changes) 之前的版本,集群名称能够在"path.data"中使用,当然系统会给一个warning警告.但是现在不允许这样使用了. 比如在之前的版本下面的配置是无效的: ~~~ # Assuming path.data is /tmp/mydata # No longer supported: $ tree /tmp/mydata /tmp/mydata ├── │ └── nodes │ └── 0 │ └── # Should be changed to: $ tree /tmp/mydata /tmp/mydata ├── nodes │ └── 0 │ └── ~~~
