> currently a tblproperty transactional=true must be set to make a table behave in ACID compliant way.
> This is misleading in that it seems like changing it to transactional=false makes the table non-acid but on disk layout of acid table is different than plain tables.  So changing this  property may cause wrong data to be returned.
> Should prevent transactional=false.
