Wenzhe Zhou reassigned IMPALA-7131:
-----------------------------------
Assignee: Wenzhe Zhou
> Support external data sources in local catalog mode
> ---------------------------------------------------
>
> Key: IMPALA-7131
> URL: https://issues.apache.org/jira/browse/IMPALA-7131
> Project: IMPALA
> Issue Type: Sub-task
> Components: Catalog, Frontend
> Reporter: Todd Lipcon
> Assignee: Wenzhe Zhou
> Priority: Minor
> Labels: catalog-v2
>
> 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.
