> Hive JDBC does not recognize UNIONTYPE columns.
> I've an external table backed by an avro schema containing a union type field.
> {noformat}
> "name" : "value",
> "type" : [ "int", "string", "null" ]
> {noformat}
> When describing the table I've:
> {noformat}
> describe test_table;
> +-------------------+---------------------------------------------------------------+----------+--+
> |     col_name      |                           data_type                           |

> {noformat}
> When doing a select query over the data using the Hive CLI, it works:
> {noformat}
> hive> select value from test_table;
> OK
> {0:10}
> {0:10}
> {0:9}
> {0:9}
> ...
> {noformat}
> But when using beeline, it fails:
> {noformat}
> 0: jdbc:hive2://....> select * from test_table;
> Error: Unrecognized column type: UNIONTYPE (state=,code=0)
> {noformat}
> By applying the patch provided with this JIRA, the command succeeds and return the expected
output.
