> Fix NPE when dropping table in HiveQueryLifeTimeHook::checkAndRollbackCTAS
> --------------------------------------------------------------------------

> Key: HIVE-27565
> URL: https://issues.apache.org/jira/browse/HIVE-27565
> Project: Hive
> Issue Type: Bug
> Reporter: zhangbutao
> Assignee: zhangbutao
> Priority: Major
> Labels: pull-request-available
>
> If dropping a iceberg table which is used by a materialized view,
> HiveQueryLifeTimeHook::checkAndRollbackCTAS will throw NPE.
>
> Step to repro:
> * create a iceberg table:
> create table test_ice1 (id int) stored by iceberg;
> * create a materialized view:
> create materialized view ice_mat1 as select * from test_ice1;
> * drop the iceberg table:
> drop table test_ice1;
