> impala-python3 shell/impala_shell.py
> create table icebergupdatet (i int, s string) stored as iceberg;
> alter table icebergupdatet set tblproperties("format-version"="2");
> delete from icebergupdatet where i=0;
> Unknown Exception : '>' not supported between instances of 'NoneType' and 'int'
> Traceback (most recent call last):

>     if is_dml and num_rows == 0 and num_deleted_rows > 0:

> The same erros should also happen when the delete removes > 0 rows, but the impala server has an older version that doesn't set TDmlResult.rows_deleted
