Thomas D'Silva commented on PHOENIX-4868:
-----------------------------------------
While dropping a column that is inherited from the parent we should store the
column as regular column with a flag saying that its excluded (instead of a
linking row). This will allow us to add back columns that were previously
dropped by validating that were are adding the column with the same type etc.
(see {{AlterTableWithViewsIT.testDivergedViewsStayDiverged()}} )
> Create a column attribute IS_EXCLUDED to denote a dropped derived column and
> remove LinkType.EXCLUDED_COLUMN
