Change subject: IMPALA-8758: Improve error message when no executors are online ...................................................................... IMPALA-8758: Improve error message when no executors are online Prior to this change a dedicated coordinator would not create the default executor group when registering its own backend descriptor in the cluster membership. This caused a misleading error message during scheduling when the default executor group could not be found. To improve this, we now always create the default executor group and return an improved error message if it is empty. This change adds a test that validates that a query against a cluster without executors returns the expected error.
