I'm using Phoenix 4.4 (HDP 2.4). I want to change some columns in an existing table to be not nullable. I was able to change the nullable property in system.catalog, but I can still upsert nulls into the changed columns.
Here's an example of what I did:
Create a simple test table
CREATE TABLE IF NOT EXISTS TEST_S.TEST_T(
ROWKEY VARCHAR NOT NULL PRIMARY KEY,
Change nullable to 0 (also tried with is_nullable)
