> Key: HADOOP-4864
> URL: https://issues.apache.org/jira/browse/HADOOP-4864
> Project: Hadoop Core
> Issue Type: Bug
> Components: filecache
> Affects Versions: 0.19.0
> Environment: When your hadoop job spans OSs.
> Reporter: Stuart White
> Priority: Minor
> Attachments: patch.txt

> Original Estimate: 1h

> When submitting a hadoop job from Windows (Cygwin) to a Linux hadoop cluster (or vice versa), and when you specify multiple additional jar files via the -libjars flag, hadoop throws a ClassNotFoundException for any classes located in the additional jars specified via the -libjars flag.
> This is caused by the fact that hadoop uses system.getProperty("path.separator") as the delimiter in the list of jar files passed via -libjars.
> My suggested solution is to use a comma as the delimiter, rather than the path.separator.
> I realize comma is, perhaps, a poor choice for a delimiter because it is valid in filenames on both Windows and Linux, but the -libjars flag uses it as the delimiter when listing the additional required jars. So, I figured if it's already being used as a delimiter, then it's reasonable to use it internally as well.
