### Description of PR JIRA: https://issues.apache.org/jira/browse/HADOOP-20062 These three methods run the path through `fixRelativePart()` and an `FSLinkResolver`, but `next(fs, p)` calls the file system with the caller's original path instead of `p`. A relative path is not resolved against the working directory: on HDFS, `fc.setStoragePolicy(new Path("dir"), "COLD")` fails with `relative paths not allowed`, while `fc.getStoragePolicy(new Path("dir"))` works. When the file system throws `UnresolvedLinkException`, the resolver retries with the link path again and ends with `Possible cyclic loop`. Every other resolver in `FileContext` passes `p`, and this patch does the same. Absolute paths without symlinks behave as before. ### How was this patch tested? Added two cases to `TestFileContext` with a mocked `AbstractFileSystem`: - `testStoragePolicyOpsQualifyRelativePath`: the three methods called with a relative path reach the file system with the path under the working directory. - `testStoragePolicyOpsFollowSymlink`: when the file system throws `UnresolvedLinkException` for a link, the three methods are applied to the link target. Without the fix the first fails on `verify` and the second with `Possible cyclic loop`. ### For code changes: - [x] Does the title of this PR start with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
