Change in behavior of public FileStatus[] globStatus(Path pathPattern, PathFilter filter)

[Subroto]

Hi,

I was running a simple unit test for verifying the behavior of a/m API. 
The UT is some thing like this:

public void testResolve_SimpleGlob() throws IOException {
        File folder = _tempFolder.newFolder("folder");
        File file1 = createFile(folder, "2010/test1");
        File file2 = createFile(folder, "2011/test1");
        File file3 = createFile(folder, "2011/test2");

        //some java code to assert
        // fileSystem.globStatus(new Path((folder.getAbsolutePath() + 
"/20*/test1")) contains path for file1 and file2
        // fileSystem.globStatus(new Path((folder.getAbsolutePath() + 
"/20*/test*")) contains path for file1, file2 and file3
        // fileSystem.globStatus(new Path((folder.getAbsolutePath() + 
"/2011/*")) contains path for file2 and file3
        // fileSystem.globStatus(new Path((folder.getAbsolutePath() + 
"/2012/*")) is empty 
    }

The fourth assertion use to work fine in cdh3u3 version but, recently while 
running the same test with cdh4b2, I encountered:
java.io.FileNotFoundException: File 
/var/folders/4w/yr852nyj3dbd1qj4w6qcwtqm0000gn/T/junit406694769891587251/folder/2012
 does not exist

Is this an intentional change made or shall we need to file it as bug and fix 
it…. ?
