>                 URL: https://issues.apache.org/jira/browse/DRILL-4812
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Storage - Other
>    Affects Versions: 1.7.0
>         Environment: Windows 7
>            Reporter: Mike Lavender

> Wildcards within the path of a query are not handled on windows and result in 
> a "String index out of range" exception.
> for example:
> {noformat}
> 0: jdbc:drill:zk=local> SELECT SUM(qty) as num FROM 
> dfs.parquet.`/trends/2016/1/*/*/3701`;
> Error: VALIDATION ERROR: String index out of range: -1
> SQL Query null
> {noformat}
> ----
> The problem exists within:
> exec\java-exec\src\main\java\org\apache\drill\exec\store\dfs\FileSelection.java
> private static Path handleWildCard(final String root)
> This function is looking for the index of the system specific PATH_SEPARATOR 
> which on windows is '\' (from System.getProperty("file.separator")).  The 
> path passed in to handleWildcard will not ever have those type of path 
> separators as the Path constructor (from org.apache.hadoop.fs.Path) sets all 
> the path separators to '/'.
> NOTE:
> private static String removeLeadingSlash(String path)
> in that same file explicitly looks for '/' and does not use the system 
> specific PATH_SEPARATOR.
