Davies Liu reassigned SPARK-6419:
---------------------------------
Assignee: Davies Liu
> GenerateOrdering does not support BinaryType and complex types.
> ---------------------------------------------------------------
>
> Key: SPARK-6419
> URL: https://issues.apache.org/jira/browse/SPARK-6419
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Yin Huai
> Assignee: Davies Liu
>
> When user want to order by binary columns or columns with complex types and
> code gen is enabled, there will be a MatchError ([see
> here|https://github.com/apache/spark/blob/v1.3.0/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/codegen/GenerateOrdering.scala#L45]).
> We can either add supports for these types or have a function to check if we
> can safely call GenerateOrdering (like the canBeCodeGened for HashAggregation
> Strategy).
