luoyuxia commented on FLINK-30030:
----------------------------------
After some investigation, the expected behavior should consider `db.tab` as a
table named db.tab, so in this case, it should throw table not found exception.
Based on such conclusion, from Flink 1.16, the behavior is as expected which
will also throw exception after FLINK-29337.
So, I will close it.

> When overwrite a table in hive dialect, it might not overwrite but to append.
> It can reproduce using the following sql:
> {code:java}
> insert overwrite table `db.tab` values (1, 2) {code}
> only happen when the table is encapsulated by backquote and the table contain
> two splits with ".".
