> The following line in HMSPathsDumper.java is causing StringIndexOutOfBoundsException:
> {code}
> if (tChildPathElement.charAt(0) == DupDetector.REPLACEMENT_STRING_PREFIX) {
> {code}
> It only happens when a path element is "", when someone mistakenly specifies hdfs path with two "/" in the path section, like hdfs://server//element1//element2, instead of hdfs://server/element1/element2. In principle, such paths are invalid, but this code should be made resistant to them anyway.
