Satish Mittal updated HIVE-7892:
--------------------------------
Status: Patch Available (was: In Progress)
> 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}
