Yin Huai commented on SPARK-13923:
----------------------------------

Please note that the temp function part of the pr is a placeholder. We will finish it in the
follow-up pr.

> Today, we have ExternalCatalog, which is dead code. As part of the effort of merging
SQLContext/HiveContext we'll parse Hive commands and call the corresponding methods in ExternalCatalog.
> However, this handles only persisted things. We need something in addition to that to
handle temporary things. The new catalog is called SessionCatalog and will internally call
ExternalCatalog.
