[jira] [Created] (SPARK-9548) BytesToBytesMap could have a destructive iterator

Josh Rosen created SPARK-9548:
---------------------------------

             Summary: BytesToBytesMap could have a destructive iterator
                 Key: SPARK-9548
                 URL: https://issues.apache.org/jira/browse/SPARK-9548
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Josh Rosen


BytesToBytesMap.iterator() could be destructive, freeing each page as it moves onto the next one.  There are some circumstances where we don't want a destructive iterator (such as when we're building a KV sorter from a map), so there should be a flag to control this.
