[jira] [Updated] (SPARK-6419) GenerateOrdering does not support
BinaryType and complex types.
[ https://issues.apache.org/jira/browse/SPARK-6419?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yin Huai updated SPARK-6419:
----------------------------
Target Version/s: 1.5.0 (was: 1.4.0)
> 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
>
> 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).
