Liang-Chi Hsieh e10b8741d8 [SPARK-16622][SQL] Fix NullPointerException when the returned value of the called method in Invoke is null ... ## What changes were proposed in this pull request? Currently we don't check the value returned by called method in `Invoke`. When the returned value is null and is assigned to a variable of primitive type, `NullPointerException` will be thrown. ## How was this patch tested? Jenkins tests. Author: Liang-Chi Hsieh <simonh@tw.ibm.com> Closes #14259 from viirya/agg-empty-ds.		2016-07-23 10:27:16 +08:00
