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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
