Apache Spark reassigned SPARK-11053:
------------------------------------
Assignee: Josh Rosen (was: Apache Spark)
> Remove use of KVIterator in SortBasedAggregationIterator
> --------------------------------------------------------
>
> Key: SPARK-11053
> URL: https://issues.apache.org/jira/browse/SPARK-11053
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Reporter: Josh Rosen
> Assignee: Josh Rosen
>
> SortBasedAggregationIterator uses a KVIterator interface in order to process
> input rows as key-value pairs, but this use of KVIterator is unnecessary,
> slightly complicates the code, and might harm performance. We should refactor
> this code to remove this use of KVIterator. I'll submit a PR to do this.
