> Doing a simple "{{ALTER TABLE testtable DROP IF EXISTS PARTITION(dt=NONEXISTENTPARTITION)}}"
fails with a SemanticException of the 10006 kind (INVALID_PARTITION).
> This does not respect the {{hive.exec.drop.ignorenonexistent}} condition either, since
there are no if-check-wraps around this area, when fetching partitions from the store.
