Hi, @ggevay, these fixes to the reduce drivers are independent of changes
to `MutableObjectIterator`. This patch is intended to fix the bug you reported
in [FLINK-3291](https://issues.apache.org/jira/browse/FLINK-3291).
+1 to improving the `MutableObjectIterator` API. Let's continue the
conversation over on
[FLINK-3291](https://issues.apache.org/jira/browse/FLINK-3291)!
