> 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 | comment |
> +-------------------+---------------------------------------------------------------+----------+--+
> | description | string | |
> | name | string | |
> | value | uniontype<int,string,void> | |
> +-------------------+---------------------------------------------------------------+----------+--+
> {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.
