--------------------------------------
https://github.com/apache/spark/pull/986
> ExternalAppendOnlyMap doesn't always find matching keys
> -------------------------------------------------------
>
> Key: SPARK-2043
> URL: https://issues.apache.org/jira/browse/SPARK-2043
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 0.9.0, 0.9.1, 1.0.0
> Reporter: Matei Zaharia
> Assignee: Matei Zaharia
> Priority: Blocker
>
> The current implementation reads one key with the next hash code as it
> finishes reading the keys with the current hash code, which may cause it to
> miss some matches of the next key. This can cause operations like join to
> give the wrong result when reduce tasks spill to disk and there are hash
> collisions, as values won't be matched together.
