Josh Rosen commented on SPARK-17453:
------------------------------------
Actually, upon closer inspection I do not believe that this is due to a race
because all TorrentBroadcast fetches are synchronized on the TorrentBroadcast
object (so only one TorrentBroadcast instance can be in the middle of a read at
any given moment).
Instead, I think that this might be a symptom of error-cleanup logic from an
earlier block manager put failure, which is why I think we'll need more logs to
debug.
Once we release 2.0.1, it would be great to confirm whether this issue has been
fixed. Is this deterministically reproducible?

> Key: SPARK-17453
> URL: https://issues.apache.org/jira/browse/SPARK-17453
> Project: Spark
> Issue Type: Bug
> Components: Block Manager, Spark Core
> Affects Versions: 2.0.0
> Reporter: Chris Bannister
>
> Whilst doing a broadcast join we reliably hit this exception, the code worked
> earlier on in 2.0.0 branch before release, and in 1.6. The data for the join
> is coming from another RDD which is collected to a Set and then broadcast.
> This is run in a Mesos cluster.
