[jira] [Created] (SPARK-14851) Support radix sort with nullable longs

Eric Liang created SPARK-14851:
----------------------------------

             Summary: Support radix sort with nullable longs
                 Key: SPARK-14851
                 URL: https://issues.apache.org/jira/browse/SPARK-14851
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
            Reporter: Eric Liang


The current radix sort cannot handle nullable longs, since there is no bit pattern available to represents nulls. These cases are probably best handled outside the radix sort logic e.g. by keeping nulls in a separate region of the array.
