[jira] [Created] (SPARK-37040) SampleExec can set outputOrdering as children's outputOrdering

chong created SPARK-37040:
-----------------------------

             Summary: SampleExec can set outputOrdering as children's outputOrdering
                 Key: SPARK-37040
                 URL: https://issues.apache.org/jira/browse/SPARK-37040
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.2.0
            Reporter: chong


All of the code paths in SampleExec that I can see preserve the child ordering, but Spark does not set this.

Is this better to set?

 override def outputOrdering: Seq[SortOrder] = child.outputOrdering
