Na Li commented on SENTRY-1773:
-------------------------------
If we support multiple Namenodes, we need to save the requested change-id for
each Namenode. To identify each Namenode, it should send both its own server
name as ID, and the changeID for perm and changeID for path.
Can we have a general table for such info? So we can add more info in the
future.
> Delta change cleaner should leave way more then a single entry intact
