Sergey Shelukhin commented on HBASE-8015:
-----------------------------------------
my point about backward compat was about the storage, not display. I.e. if
people want to create a table "a.b" without namespace and be confused while
viewing some table list, I think it's ok. Maybe we can disallow tables with
dots.
If they have existing table "a.b" and NS is stored separately, again the worst
thing that happens is user gets confused, reads the release notes and renames
it. Should be ok to.
But if we /store/ NS in table name, then with table a.b, without special
handing, system gets confused (thinks it's in NS "a") after upgrade :)
