[jira] [Commented] (SPARK-16452) basic INFORMATION_SCHEMA support

    [ https://issues.apache.org/jira/browse/SPARK-16452?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17026184#comment-17026184 ] 

Aaron Steers commented on SPARK-16452:
--------------------------------------

Hello, everyone. I would like to revitalize this thread. Is there any plan to add support for INFORMATION_SCHEMA, which is part of SQL92?

Any possibility of revitalizing SPARK-16492 or implementing in another way? That PR (marked stale/closed in 2016) references a possible future dependency on something called "Catalog Federation" and goal to pick this up again after that was delivered - do we know if that federation has been implemented or is it still in the plan, and if not, is there another a viable path forward?

I think this is a hugely important feature for Spark and I'm willing to help contribute if I could get direction on a possible path forward.
