> This is a bug introduced by IMPALA-9936 in which we added the DCHECK. This
> use case is still sending back the full DB object to the coordinator.
> For reproducing the issue:
> {code:sql}
> # Start Impala cluster with --hms_event_polling_interval_s=0
> bin/start-impala-cluster.py --catalogd_args="--catalog_topic_mode=minimal
> --hms_event_polling_interval_s=0" --impalad_args=--use_local_catalog
> # Create new db and new table in Hive
> beeline -u "jdbc:hive2://localhost:11050"
> > create database mydb;
> > create table mydb.mytbl (i int);
> # Run IM in Impala
> impala-shell.sh
> > invalidate metadata mydb.mytbl;
> # The coordinator will crash at hitting the DCHECK
> {code}
