Jean-Daniel Cryans updated HBASE-3650:
--------------------------------------
Attachment: HBASE-3650.patch
This patch adds a new utility in MetaReader to configure a Scan that only reads
the rows from a single table, then refactors both HBA and MetaReader to use it.
Finally it adds a test to make sure the method is getting the right rows from
.META.
> HBA.delete can return too fast

> 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.
