其实这个错误是很搞笑的。你用tiup 安装tidb cluster ,出现一行字
Attention:
1. If the topology is not what you expected, check your yaml file.
2. Please confirm there is no port/directory conflicts in same host.
Do you want to continue? [y/N]: (default=N)
在这个时候,如果你输入y,自然是开始安装,输入N就退出安装。但是你要是什么字符都不输入,然后回车,或者输入的字符不是y或者n,然后回车,结果就报错:Error: Operation aborted by user answer '' (cliutil.operation_aborted) 。就是这么简单
