----------------------------------
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.
