Subject [jira] [Commented] (HIVE-12064) prevent transactional=false

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.

> 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.
