[jira] [Created] (SPARK-16167) RowEncoder should preserve array/map type nullability.

Takuya Ueshin created SPARK-16167:
-------------------------------------

             Summary: RowEncoder should preserve array/map type nullability.
                 Key: SPARK-16167
                 URL: https://issues.apache.org/jira/browse/SPARK-16167
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Takuya Ueshin


Currently {{RowEncoder}} doesn't preserve nullability of {{ArrayType}} or {{MapType}}.
It returns always {{containsNull = true}} for {{ArrayType}}, {{valueContainsNull = true}} for {{MapType}} and also the nullability of itself is always {{true}}.
