> In my windows env, when I run Kylin, Kylin service can't start. In class ZKUtil, I found
Kylin use File(path).getCanonicalPath() to norm windows path, however this will get a path
like ' C:\kylin\kylin_metadata'.For Zookeeper, the path must start with / character.
> {color:#FF0000}return new File(path).toURI().getPath(){color} might be better!!!
