------------------------------------
Summary: Coordinator unnecessarily invalidating locally cached
table metadata
Key: IMPALA-9848
URL: https://issues.apache.org/jira/browse/IMPALA-9848
Project: IMPALA
Issue Type: Improvement
Components: Catalog, Frontend
Reporter: Sahil Takiar
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.
