Chinmay Kulkarni updated PHOENIX-5958:
--------------------------------------
Description:
By "diverged view" I mean creating a view and then dropping one of the
inherited columns from the view. Steps to reproduce:
Start a 4.x server and connect with a pre-4.15 (I tried a 4.14.3) client
CREATE TABLE IF NOT EXISTS S.T (A INTEGER PRIMARY KEY, B INTEGER);
CREATE VIEW IF NOT EXISTS S.V (new_col INTEGER) AS SELECT * FROM S.T;
UPSERT INTO S.T VALUES(1,2);
ALTER VIEW S.V DROP COLUMN B;
SELECT * FROM S.T;
gives:
|A|B|
|1|2|
SELECT * FROM S.V; gives:
|B|A|NEW_COL|
|2|1|null|
Though the column 'B' has been dropped from the view. This does not happen for
a 4.x client.
The problem is mostly due to changes introduced by
[PHOENIX-4893|https://issues.apache.org/jira/browse/PHOENIX-4893].
