----------------------------------
Summary: Support parameters for UDTs
Key: SPARK-14054
URL: https://issues.apache.org/jira/browse/SPARK-14054
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 1.6.1
Reporter: Kevin Chen
Priority: Minor
Currently UDTs with parameters, e.g. generic types are not supported. Json
serialized UDTs are instantiated with reflection by a parameter-less
constructor (DataType.fromJson). This means a user needs to create a separate
UDT for types that differ only in generic types, e.g. one backed by a list of
string and another backed by a list of integer.
