-----------------------------------------
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).
