[jira] [Created] (ARROW-2538) [Java] Introduce FieldWriter.writeNull method

Teddy Choi created ARROW-2538:

             Summary: [Java] Introduce FieldWriter.writeNull method
                 Key: ARROW-2538
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java - Vectors
            Reporter: Teddy Choi
            Assignee: Teddy Choi

When a data set has null values in complex data type, it's hard to call proper writeNull method. Because writeNull is declared in AbstractFieldWriter, which is package local, not public. Moreover, UnionListWriter has no implementation of writeNull method, so it falls into AbstractFieldWriter.writeNull, which throws an IllegalArgumentException by default. So FieldWriter.writeNull is required to write null values inside of complex data types.
