> Thrift supports List, Map and Struct complex types, which get mapped to Array, Map and Struct complex types in Hive respectively. However thrift Set type doesn't seem to be working. 
> Here is an example thrift struct:
> {noformat}
> namespace java sample.thrift
> struct setrow {
>     1: required set<i32> ids,
>     2: required string name,
> }
> {noformat}
> A Hive table is created with ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.thrift.ThriftDeserializer' WITH SERDEPROPERTIES ('serialization.class'='sample.thrift.setrow', 'serialization.format'='org.apache.thrift.protocol.TBinaryProtocol').
> Describing the table shows:
> {noformat}
> hive> describe settable; 
> OK
> ids                 	struct<>            from deserializer   
> name                string              	from deserializer
> {noformat}
> Issuing a select query on set column throws SemanticException:
> {noformat}
> hive> select ids from settable;
> FAILED: SemanticException java.lang.IllegalArgumentException: Error: name expected at the position 7 of 'struct<>' but '>' is found.
> {noformat}
