Marco Gaido 3887b7eef7 [SPARK-22665][SQL] Avoid repartitioning with empty list of expressions ... ## What changes were proposed in this pull request? Repartitioning by empty set of expressions is currently possible, even though it is a case which is not handled properly. Indeed, in `HashExpression` there is a check to avoid to run it on an empty set, but this check is not performed while repartitioning. Thus, the PR adds a check to avoid this wrong situation. ## How was this patch tested? added UT Author: Marco Gaido <marcogaido91@gmail.com> Closes #19870 from mgaido91/SPARK-22665.		2017-12-04 17:08:56 -08:00
