Gopal V commented on HIVE-18727:
--------------------------------
The files need APL license headers and it is important to rename HiveError as
DataConstraintViolationError and include information about the row/column which
has the issue (column is more important than the row, row is easy to find with
a "where col is null").
> Update GenericUDFEnforceNotNullConstraint to throw an ERROR instead of
> Exception on failure

> Throwing an exception makes TezProcessor stop retrying the task. Since this
> is NOT NULL constraint violation we don't want TezProcessor to keep retrying
> on failure.
