Doug Cutting commented on HADOOP-905:
-------------------------------------
Yes, this looks like dead code, left over from a prior version. It should be
removed, as the paths are now fully-qualified in InputFormatBase. Thanks for
noticing this!
> Code to qualify inputDirs doesn't affect path validation
> --------------------------------------------------------

> Key: HADOOP-905
> URL: https://issues.apache.org/jira/browse/HADOOP-905
> Project: Hadoop
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.10.1
> Reporter: Kenji Matsuoka
>
> 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);
