Another data point -- I've seen this happen (in 2.3.0) during cleanup after a
task failure:

> Key: SPARK-22371
> URL: https://issues.apache.org/jira/browse/SPARK-22371
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.1.0
> Reporter: Mayank Agarwal
> Priority: Major
> Attachments: Helper.scala, ShuffleIssue.java,
> driver-thread-dump-spark2.1.txt, sampledata
>
>
> Our Spark Jobs are getting stuck on DagScheduler.runJob as dagscheduler
> thread is stopped because of *Attempted to access garbage collected
> accumulator 5605982*.
> from our investigation it look like accumulator is cleaned by GC first and
> same accumulator is used for merging the results from executor on task
> completion event.
> As the error java.lang.IllegalAccessError is LinkageError which is treated as
> FatalError so dag-scheduler loop is finished with below exception.
> ---ERROR stack trace --
