SPARK-7768

> Add support for Joda-time types

>                 Key: SPARK-6875
>                 URL: https://issues.apache.org/jira/browse/SPARK-6875
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>            Reporter: Patrick Grandjean

> The need comes from the following use case:
> val objs: RDD[MyClass] = [...]
> val sqlC = new org.apache.spark.sql.SQLContext(sc)
> import sqlC._
> objs.saveAsParquetFile("parquet")
> MyClass contains joda-time fields. When saving to parquet file, an exception is thrown (matchError in ScalaReflection.scala).
> Spark SQL supports java SQL date/time types. This request is to add support for Joda-time types. 
> It is possible to define UDT's using the @SQLUserDefinedType annotation. However, in addition to annotations, it would be nice to be able to programmatically/dynamically add UDTs.
