Description

Currently at few instances , reserved paths are resolved without checking for permission, even if "dfs.permissions.enabled" is set to true.

    FSPermissionChecker pc = fsd.getPermissionChecker();
    byte[][] pathComponents = FSDirectory.getPathComponentsForReservedPath(src);
    INodesInPath iip;
    fsd.writeLock();
    try {
      src = *FSDirectory.resolvePath(src, pathComponents, fsd);*
