[jira] [Created] (IMPALA-14906) Throw errors on NULL for non-nullable columns

Zoltán Borók-Nagy created IMPALA-14906:
------------------------------------------

             Summary: Throw errors on NULL for non-nullable columns
                 Key: IMPALA-14906
                 URL: https://issues.apache.org/jira/browse/IMPALA-14906
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Zoltán Borók-Nagy


We can specify columns as non-nullable, e.g.:

{noformat}
CREATE TABLE t (i INT NOT NULL)
STORED AS ICEBERG;
{noformat}

Writers should not write NULLs into such tables. But it can still happen by non-compliant writers. In this case Impala could detect forbidden NULLs during read and raise an error.
