> When enabling `enable_workload_mgmt` in a cluster, the impalad failed to start with a FATAL error:
> {code:java}
> F0710 17:46:51.211848 456937 workload-management.cc:346] AnalysisException: Database does not exist: sys. Impalad exiting. {code}
> There was also a db creation error in the log before this error happened:
> {code:java}
> I0710 17:46:51.169672 456951 client-request-state.cc:1348] 744c895a3184553c:0759f54000000000] IllegalStateException: Can't create blacklisted database: sys. --blacklisted_dbs may be inconsistent between catalogd and coordinators {code}
> We must change the default value of the impalad/catalogd flag 'blacklisted_dbs' to enable the query log table. Maybe we should add a validator for 'enable_workload_mgmt' to avoid any conflicts.
