Description

In the Spark SQL thrift interface the GetResultSetMetadata reply packet that describes the result set metadata, reports a column that is defined as a VARCHAR in the database, as Native type of STRING. Data still returns correctly in the thrift string type but ODBC/JDBC is not able to correctly describe the data type being return or its defined maximum length.

FYI Hive returns it correctly.
