At present, failure in event processing needs manual invalidate metadata. This patch implicitly invalidates the table upon failures in processing of table events with new 'invalidate_metadata_on_event_processing_failure' flag. And a new 'invalidate_global_metadata_on_event_processing_failure' flag is added to global invalidate metadata automatically when event processor goes to non-active state. Note: Also introduced a config 'inject_process_event_failure_event_types' for automated tests to simulate event processor failures. This config is used to specify what event types can be intentionally failed. This config should only be used for testing purpose. Need IMPALA-12851 as a prerequisite Testing: - Added end-to-end tests to mimic failures in event processor and verified that event processor is active - Added unit test to verify the 'auto_global_invalidate_metadata' config - Passed FE tests Co-Authored-by: Sai Hemanth Gantasala <saihemanth@cloudera.com> Change-Id: Ia67fc04c995802d3b6b56f79564bf0954b012c6c Reviewed-on: http://gerrit.cloudera.org:8080/21065 Reviewed-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
