Julien Le Dem commented on PIG-2957:
------------------------------------
could you call the method something more explicit than "cleanupPath". Something
like "getPathForJar" maybe?
Also add comments to explain what exactly this is doing:
{noformat}
if (path.charAt(1)==':') {
newPath = path.charAt(0) + path.substring(2);
}
{noformat}
It would be useful to describe what it is changing in the path and why.
In particular the drive letter becomes a root dir in the jar (C:/foo becomes
C/foo). If that's what we want then it should be clearer.
