---------------------------------
Summary: Replace existing analysis.Catalog with SessionCatalog
Key: SPARK-14014
URL: https://issues.apache.org/jira/browse/SPARK-14014
Project: Spark
Issue Type: Bug
Reporter: Andrew Or
Assignee: Andrew Or
As of this moment, there exist many catalogs in Spark. For Spark 2.0, we will
have two high level catalogs only: SessionCatalog and ExternalCatalog.
SessionCatalog (implemented in SPARK-13923) keeps track of temporary functions
and tables and delegates other operations to ExternalCatalog.
At the same time, there's this legacy catalog called `analysis.Catalog` that
also tracks temporary functions and tables. The goal is to get rid of this
legacy catalog and replace it with SessionCatalog, which is the new thing.
