------------------------------------------
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.
