+1. The test failure looks unrelated.

> Currently for an typical namenode operation a path can be resolved multiple
> times. Usually the FSPermissionChecker first takes the path string as input
> and resolve the path before the real checking. After permission checking the
> path is then resolved again (and again) for real operations in FSNamesystem
> and FSDirectory. Ideally we should resolve the path only once, and use
> INodesInPath internally afterwards. As a first step, we can start from
> avoiding path resolving in FSPermissionChecker.
