> Catalogd caches the table and partition metadata. If an external FE needs to
> be supported to query using the Impala, it would need to get this metadata
> from catalogd to compile the query and generate the plan. While a subset of
> the metadata which is cached in catalogd, is sourced from Hive metastore, it
> also caches file metadata which is needed by the Impala backend to create the
> Impala plan. It would be good to expose the table and partition metadata
> cached in catalogd over HMS API so that any Hive metastore client (e.g spark,
> hive) can potentially use this metadata to create a plan. This JIRA tracks
> the work needed to expose this information over catalogd.
