             Summary: ZKUtil acquire the wrong Zookeeper Path on windows
                 Key: KYLIN-3935
                 URL: https://issues.apache.org/jira/browse/KYLIN-3935
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v2.6.1
            Reporter: Na Zhai
            Assignee: Na Zhai
             Fix For: v2.6.2


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!!!
