["Todd Lipcon (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IMPALA-7506?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Todd Lipcon updated IMPALA-7506:
--------------------------------
    Description: There is some complexity with how this is implemented in the original code: it depends on maintaining the minimum version of any object in the impalad's local cache. We can't determine that in an on-demand impalad, so INVALIDATE METADATA is not supported currently on "fetch-on-demand".  (was: There is some complexity with how this is implemented in the original code: it depends on maintaining the minimum version of any object in the impalad's local cache. We can't determine that in an on-demand impalad, so SYNC_DDL + INVALIDATE METADATA is not supported currently on "fetch-on-demand".)
        Summary: Support global INVALIDATE METADATA on fetch-on-demand impalad  (was: Support INVALIDATE METADATA with SYNC_DDL on fetch-on-demand impalad)
