Code to qualify inputDirs doesn't affect path validation

This code, at JobClient:306, doesn't seem to validate the fully qualified inputDirs, since inputDirs is a newly created arrray:

Path[] inputDirs = job.getInputPaths();

// make sure directories are fully qualified before checking them
for(int i=0; i < inputDirs.length; ++i) {
if (inputDirs[i].toUri().getScheme() == null)

{ inputDirs[i] = userFileSys.makeQualified(inputDirs[i]); }

}

// input paths should exist.
job.getInputFormat().validateInput(job);
