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

> 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.
