[jira] [Updated] (SPARK-2104) RangePartitioner should use user
specified serializer to serialize range bounds
[ https://issues.apache.org/jira/browse/SPARK-2104?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Reynold Xin updated SPARK-2104:
-------------------------------
Description:
Otherwise it is pretty annoying to do a sort on types that are not java serializable.
To reproduce, just set the serializer to Kryo, and run the following job:
{code}
class JavaNonSerializableClass extends Comparable { override def compareTo(o: JavaNonSerializableClass) = 0 }
sc.parallelize(Seq(new JavaNonSerializableClass, new JavaNonSerializableClass), 2).map(x => (x,x)).sortByKey()
{code}
