Todd Lipcon commented on IMPALA-7438:
-------------------------------------

I think this is more or less covered by TestLocalCatalogRetries that Vuk and I 
worked on in 5cc49c343f8 and 94cfdac664c

> Automated test for concurrent DDL and metadata queries

> The "localcatalog" implementation has some special provisions to ensure that 
> queries are planned on consistent snapshots, and any inconsistencies are 
> detected and resolved by retries. In IMPALA-7436 I tested this manually, but 
> we should write an automated regression test for this functionality.
