> Spark Runner Fails on Certain Versions of Spark 2.X
> ---------------------------------------------------
>
> Key: BEAM-6771
> URL: https://issues.apache.org/jira/browse/BEAM-6771
> Project: Beam
> Issue Type: Bug
> Components: runner-spark
> Affects Versions: 2.11.0
> Reporter: Kyle Winkelman
> Assignee: Kyle Winkelman
> Priority: Blocker
> Time Spent: 1.5h
> Remaining Estimate: 0h

> When updating to Beam 2.11.0, I ran into the exception at the bottom of this issue while running a pipeline on the Spark Runner (which worked in 2.9.0). My cluster uses Spark 2.2.1.
> Related Issues:
> SPARK-23697 (Proof that equals must be implemented for items being accumulated.)
> BEAM-1920 (In PR#3808, equals was implemented on MetricsContainerStepMap to get Spark to run on 2.X.)
> My analysis has lead me to believe that BEAM-6138 is the reason for this issue.
> Before this change, versions of Spark that are affected by SPARK-23697 would create a new MetricsContainerStepMap and make sure that the copied and reset instance (the one serialized for distribution) is equal to the initial empty MetricsContainerStepMap that is passed in. This would effectively check if two empty ConcurrentHashMaps were equal. This results in true.
> After this change, versions of Spark that are affected by SPARK-23697 would effectively be checking if two empty ConcurrentHashMaps were equal _*AND*_ if two different instances of the MetricsContainerImpl are equal. Because MetricsContainerImpl doesn't implement equals, this results in false.
> I believe BEAM-6546 will fix this issue, but I wanted to raise a red flag. I am also hoping someone can verify my analysis.
