---------------------------------------
[~samarthjain] - what do you think? If you agree, would you mind tweaking your
recent change that went in for PHOENIX-1504?
> Allow view with views to add column

> Key: PHOENIX-2055
> URL: https://issues.apache.org/jira/browse/PHOENIX-2055
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor

> Minor follow on to PHOENIX-1504. Due to the potential slowness of the check
> for whether or not a view has views, especially as the number of views
> increases (see PHOENIX-2051), I think we should remove the check you added
> for disallowing adding a column to a view with views. I think it's important
> to maintain good performance of adding a column to a view. The net effect of
> allowing the addition of a column to view with views is that all the child
> views will be considered to have diverged from their parent (which isn't the
> end of the world). Though somewhat painful, a user could always manually add
> the column to the child views if desired.
