Stamatis Zampetakis commented on HIVE-26924:
--------------------------------------------
>From the description of the ticket it is not clear what happens after the
>SemanticException is raised. Will the queries following the exception be able
>to exploit the view or not? Naturally I would think no but I am not sure how
>to interpret the following:
{noformat}
>>> alter materialized view mv_rewrite enable rewrite;
>>> explain select si,t from all100k where t>116 and t<120;
!!! match row_contains
alias: iceberg_test_db_hive.mv_rewrite
{noformat}
Can you please clarify [~dharmikt] [~kkasa]?
