Sameer Agarwal 09b3c56c91 [SPARK-14752][SQL] Explicitly implement KryoSerialization for LazilyGenerateOrdering ... ## What changes were proposed in this pull request? This patch fixes a number of `com.esotericsoftware.kryo.KryoException: java.lang.NullPointerException` exceptions reported in [SPARK-15604], [SPARK-14752] etc. (while executing sparkSQL queries with the kryo serializer) by explicitly implementing `KryoSerialization` for `LazilyGenerateOrdering`. ## How was this patch tested? 1. Modified `OrderingSuite` so that all tests in the suite also test kryo serialization (for both interpreted and generated ordering). 2. Manually verified TPC-DS q1. Author: Sameer Agarwal <sameer@databricks.com> Closes #13466 from sameeragarwal/kryo.		2016-06-02 10:58:00 -07:00
