Thomas D'Silva commented on PHOENIX-4893:
-----------------------------------------
We would need to still support sending a PTable with all the ancestor columns
to maintain b/w compatibility with an old client. For new clients we can make
return the PTable with only the current view/view index columns and then make
separate calls to fetch the ancestors and combine columns on the client side.
> Phoenix scans SYSCAT region from RegionServerCoprocessor

> Key: PHOENIX-4893
> URL: https://issues.apache.org/jira/browse/PHOENIX-4893
> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Lars Hofhansl
> Priority: Major
>
> In a stack trace I see that phoenix.coprocessor.ViewFinder.findRelatedViews()
> scans SYSCAT. With splittable SYSCAT which now involves regions from other
> servers.
> We should really push this to the client now.
> Related to HBASE-21166
