Attila Magyar commented on HIVE-21666:
--------------------------------------

[~tlipcon], alter table goes through the same validation
{code:java}
> create table aaa(key int) stored as orc;
> ALTER TABLE aaa SET TBLPROPERTIES ('transactional_properties'='insert_only');
Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
Cannot set 'transactional_properties' to 'insert_only' without setting 'transactional' to
'true' (state=08S01,code=1){code}

> I created a table with 'transactional_properties'='insert_only' but didn't specify 'transactional'='TRUE'.
I was able to insert into this table, but when I tried to query it, I got a NumberFormatException
since it appears the insert path used a non-transactional layout while the read path expected
one.
