> Yes，the src is not the dst path, but we can use the src to lookup real dst path in mount table. Here, we can not execute this.subclusterResolver.getMountPoints(path);, because the statement is time-consuming. From correctness point of view it isn't correct. If ``/mount/path`` points to Ns0 ``/dir`` and we log`` /mount/path`` in the namenode, it can lead to confusions if the namenode also has a path named ``/mount/path``, If you operate on ``/dir`` via router ``/mount/path`` and if you directly operate on ``/mount/path`` on the namenode. If it has serious performance penalties we need to make it configurable and then figure out what can be done when the config is disabled. -- This is an automated message from the Apache Git Service.
