-----------------------------------
Summary: Thrift Set type not working with Hive
Key: HIVE-7892
URL: https://issues.apache.org/jira/browse/HIVE-7892
Project: Hive
Issue Type: Bug
Components: Serializers/Deserializers
Reporter: Satish Mittal
Assignee: Satish Mittal
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}
