> After recent update of Hive hook, to replace use of V1 notifications with V2 notifications (ATLAS-2491), 'alter view as' operation results in incorrect metadata update. Consider the following Hive statements which create a view and followed by an alter view:
> {code}
> create table table1(col1 int, col2 string);
> create table table2(col3 date , col4 string);
> create view view1 as select * from table1;
> alter view view1 as select * from table2;
> {code}
> With earlier Hive hook implementation, after "alter view as", 'view1' would have columns col1 and col2 as DELETED and col3, col4 as ACTIVE.
> After update in ATLAS-2491, view1 continues to show col1 and col2 in ACTIVE state; and doesn't have col3 and col4 columns.
