Himanshu Vashishtha commented on HBASE-10581:
---------------------------------------------
Yeah, I okay'ed it in my last comment considering such odd usages…
But IMHO, any non-hbase process creating arbitrary znodes under /hbase doesn't
sound right.
If we treat it similar to creating arbitrary files in hbase directory, then a
recursive delete of such znodes is the right option (and doc it accordingly in
the book).
Having said that, I am still okay if we don't delete them. :)
