gbloisi commented on issue #23074: [SPARK-19798][SQL] Refresh table does not have effect on other sessions than the issuing one URL: https://github.com/apache/spark/pull/23074#issuecomment-475576758 A spark shell example is provided with https://issues.apache.org/jira/browse/SPARK-19798. The provided test is put in HiveMetadataCacheSuite because there I found a very similar test to modify and show the problem, but I think it is reproducible with any data store that requires some level of refreshing in case of concurrent changes: the potentially stale data is from the cache in the sessionCatalog and this cache does not get refreshed across sessions.
