> The following fails when run locally on master:
> {code:java}
> ./bin/start-impala-cluster.py --catalogd_args='--catalog_topic_mode=minimal' --impalad_args='--use_local_catalog'
> ./bin/impala-shell.sh
> [localhost:21000] default> select count(l_comment) from tpch.lineitem; <--- THIS WORKS
> # kill the catalogd process
> [localhost:21000] default> select count(l_comment) from tpch.lineitem; <--- THIS FAILS
> ERROR: AnalysisException: Failed to load metadata for table: 'tpch.lineitem'
> CAUSED BY: TableLoadingException: Could not load table tpch.lineitem from catalog
> CAUSED BY: TException: org.apache.impala.common.InternalException: Couldn't open transport for localhost:26000 (connect() failed: Connection refused)CAUSED BY: InternalException: Couldn't open transport for localhost:26000 (connect() failed: Connection refused {code}
> The above experiment works with catalog v1 - e.g. if you remove the startup flags in the {{./bin/start-impala-cluster.py}} everything works.
