[jira] [Created] (SPARK-17761) Simplify InternalRow hierarchy

Herman van Hovell created SPARK-17761:

             Summary: Simplify InternalRow hierarchy
                 Key: SPARK-17761
                 URL: https://issues.apache.org/jira/browse/SPARK-17761
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Herman van Hovell
            Assignee: Herman van Hovell


The current InternalRow hierarchy makes a difference between immutable and mutable rows. In practice we cannot guarantee that an immutable internal row is immutable (you can always pass a mutable object as an one of its elements). Lets make all internal rows mutable (and reduce the complexity).
