*	[SPARK-17551][SQL] Add DataFrame API for null ordering	xin wu	2016-09-25	1	-0/+254
	## What changes were proposed in this pull request? This pull request adds Scala/Java DataFrame API for null ordering (NULLS FIRST \| LAST). Also did some minor clean up for related code (e.g. incorrect indentation), and renamed "orderby-nulls-ordering.sql" to be consistent with existing test files. ## How was this patch tested? Added a new test case in DataFrameSuite. Author: petermaxlee <petermaxlee@gmail.com> Author: Xin Wu <xinwu@us.ibm.com> Closes #15123 from petermaxlee/SPARK-17551.
