[jira] [Created] (IMPALA-7131) Support external data sources without catalogd

Todd Lipcon created IMPALA-7131:
-----------------------------------

             Summary: Support external data sources without catalogd
                 Key: IMPALA-7131
                 URL: https://issues.apache.org/jira/browse/IMPALA-7131
             Project: IMPALA
          Issue Type: Sub-task
          Components: Catalog, Frontend
            Reporter: Todd Lipcon


Currently it seems that external data sources are not persisted except in memory on the catalogd. This means that it will be somewhat more difficult to support this feature in the design of impalad without a catalogd.

This JIRA is to eventually figure out a way to support this feature -- either by supporting in-memory on a per-impalad basis, or perhaps by figuring out a way to register them persistently in a file system directory, etc.
