Description

Checks in Status KuduSession::Data::ValidateWriteOperation on the C++ side, segfault in the Python client.
I noticed this while writing tests for the auto-incrementing column feature:
Repro:

            op = table.new_insert()
            op['key'] = 1
            op[Schema.get_auto_incrementing_column_name()] = 1
            error_msg = 'should not be specified for Insert operation'
            with self.assertRaisesRegex(KuduBadStatus, error_msg):
                session.apply(op)

e.g.: inserting, while having a auto-incrementing column specified: raises the error correctly, but in the end it segfaults:
