[jira] [Created] (HADOOP-10798) globStatus() does not return sorted
list of files
Felix Borchers created HADOOP-10798:
---------------------------------------
Summary: globStatus() does not return sorted list of files
Key: HADOOP-10798
URL: https://issues.apache.org/jira/browse/HADOOP-10798
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.3.0
Reporter: Felix Borchers
Priority: Minor
(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.
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}
