> Key: HADOOP-16971
> URL: https://issues.apache.org/jira/browse/HADOOP-16971
> Project: Hadoop Common
> Issue Type: Bug
> Components: common, test
> Affects Versions: 3.2.1, 3.4.0
> Reporter: Ctest
> Priority: Minor
> Labels: easyfix
> Attachments: HADOOP-16971.000.patch

>
> In the test `testFileContextResolveAfs`, the symlink
> `TestFileContextResolveAfs2` (linked to `TestFileContextResolveAfs1`) was not
> deleted as intended in the first run, thus the test will fail in the second
> run.
> The reason is that this test uses org.apache.hadoop.fs.FileSystem to handle
> the deletion of symlink, which
> 1. does not support symlink.
> 2. deletes `TestFileContextResolveAfs1` before `TestFileContextResolveAfs2`
> if both links passed into `deleteOnExit` in any order, because of the
> ordering of paths to be deleted in the TreeSet `deleteOnExit`.
> When `TestFileContextResolveAfs1` has been deleted,
> `TestFileContextResolveAfs2` became an orphan symlink and is now considered
> as a non-exisitent path by org.apache.hadoop.fs.FileSystem, thus its deletion
> cannot be completed.
