Qiuzhuang Lian commented on HIVE-12064:
---------------------------------------
Yes, code seems to check this condition. It is incompatible with 1.X which
seems OK. At least, this should be put into documentation. I did create the
ORC table without transaction enabled from txt table and it works.
> prevent transactional=false

> 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.
