--------------------------------------

             Summary: Make ColumnarBatch.Row mutable
                 Key: SPARK-14320
                 URL: https://issues.apache.org/jira/browse/SPARK-14320
             Project: Spark
          Issue Type: Sub-task
            Reporter: Sameer Agarwal


In order to leverage a data structure like `AggregateHashmap` (https://issues.apache.org/jira/browse/SPARK-14263) to speed up aggregates with keys, we need to make ColumnarBatch.Row mutable.
