filter)

>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
