Jinglun commented on HDFS-15973:
--------------------------------
Submit the initial patch. The patch introduces the RouterINode class to save
the file status. First it collects the file status of the src and the dst and
saves to the RouterINode array. Then it uses RouterPermissionChecker(very like
the FsPermissionChecker) to do the permission check.
> RBF: Add permission check before doting router federation rename.
