Alexander Kolbasov commented on SENTRY-1773:
--------------------------------------------
Why would Sentry server need a knowledge about NameNode change IDs? It is up to
NN to keep track of what IDs it processed or not - the server just manages
snapshots and deltas. As long as deltas are available it can send them. I don't
see a reason the server should ever record NN ideas of IDs.
> Delta change cleaner should leave way more then a single entry intact
