             Summary: Add method to get path start position without drive specifier in o.a.h.fs.Path  
                 Key: HADOOP-9897
                 URL: https://issues.apache.org/jira/browse/HADOOP-9897
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Binglin Chang
            Assignee: Binglin Chang
            Priority: Trivial


There are a lot of code in Path to get start position after skipping drive specifier, like:

{code}
    int start = hasWindowsDrive(uri.getPath()) ? 3 : 0;
{code}

First, using hard coded 3 or 0 is bad, second, the code always assumes path is with "/" prefix.
