Jean-Daniel Cryans commented on HBASE-3650:
-------------------------------------------
Here's what we accept in tables' names:
{code}
Character.isLetterOrDigit(b[i]) || b[i] == '_' || b[i] == '-' ||
b[i] == '.'
{code}
So Space is smaller than any of those.
I'll clean the rest, thanks for taking a look!

> One of our engineers got a weird TableExistsException in his code and I see
> that the client-side logging says the table was deleted in less than a second
> while it took the master 5 seconds to do it. Doing code inspection, the
> .META. scanner in HBA.delete can set _found_ to _true_ and then set it back
> to _false_ in the case where the deleted table isn't the last one. We should
> just do a scan that would get the rows specific to the table instead of
> scanning *all* the rows.
