Support external data sources in local catalog mode

Details

    • ghx-label-3

    Description

      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.
