> HADOOP-5266 introduced support for Mark/Reset of Values Iterator by backing
> up keys and values to a BackupStore. The current design does not create a
> memory segment once a file segment has been created, even if space is
> available. The design could be optimized to consider memory for a new segment
> irrespective of where the previous segments have been created.
