> [~alanj_impala_5a78] reports that the error message was a little confusing here:
> {noformat}
> [localhost:21000] default> create table test_null_field as select null as null_field;
> Query: create table test_null_field as select null as null_field
> Query submitted at: 2018-10-08 12:18:40 (Coordinator: http://tarmstrong-box:25000)
> ERROR: AnalysisException: Unsupported type 'null_type' in column 'null_field' of table 'test_null_field'
> CAUSED BY: TableLoadingException: Unsupported type 'null_type' in column 'null_field' of table 'test_null_field'
> {noformat}
> I grepped the code and it doesn't look like we actually have a targeted test, so we should add the coverage too.
