Mitesh updated SPARK-16419:
---------------------------
Description: EnsureRequirements compares the required and given sort
ordering, but uses Scala equals instead of a semantic equals, so column
capitalization isn't considered, and also fails for a cached table. This
results in a SortMergeJoin of a cached already-sorted table to add an extra
sort. (was: EnsureRequirements compared the required and given sort ordering,
but uses Scala equals instead of a semantic equals, so column capitalization
isn't considered.)
