[jira] [Commented] (HADOOP-10798) globStatus() does not return sorted list of files

["Daryn Sharp (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-10798?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14054930#comment-14054930 ] 

Daryn Sharp commented on HADOOP-10798:
--------------------------------------

Which filesystem?  Ie. hdfs or local?  GlobStatus should return a sorted list because it calls listStatus which returns a sorted list.  If the glob results are not sorted, then listStatus is likely the culprit.

> (FileSystem) globStatus() does not return a sorted file list anymore.
> But the API says: " ... Results are sorted by their names."
> Seems to be lost, when the Globber Object was introduced. Can't find a sort in actual code.
> code to check this behavior:
> {code}
>         Configuration conf = new Configuration();
>         FileSystem fs = FileSystem.get(conf);
>         Path path = new Path("/tmp/" + System.currentTimeMillis());
>         fs.mkdirs(path);
>         fs.deleteOnExit(path);
>         fs.createNewFile(new Path(path, "2"));
>         fs.createNewFile(new Path(path, "3"));
>         fs.createNewFile(new Path(path, "1"));
>         FileStatus[] status = fs.globStatus(new Path(path, "*"));
>         Collection list = new ArrayList();
>         for (FileStatus f: status) {
>             list.add(f.getPath().toString());
>             //System.out.println(f.getPath().toString());
>         }
>         boolean sorted = Ordering.natural().isOrdered(list);
>         Assert.assertTrue(sorted);
> {code}
