Hi, I am wondering if anyone has been able to get Thrift Set type working in Hive.
Thrift supports List, Map and Struct complex types, which get mapped to Array, Map and Struct complex types in Hive respectively. (Though there is a difference in the support for Map: Thrift map allows a key of complex type whereas Hive map doesn't.) However thrift Set type doesn't seem to be working. Here is an example thrift struct: struct setrow { 1: required set<i32> ids, 2: required string name, } I created a Hive table using ThriftDeserializer as the serde class and serialization.class is set to above thrift java class. However a describe on this table shows type of column 'ids' as struct<>. Also issuing a select query on set column throws SemanticException: FAILED: SemanticException java.lang.IllegalArgumentException: Error: name expected at the position 7 of 'struct<>' but '>' is found. Any pointers/thoughts?
