> It looks like some of the AccumulatorSuite tests have started failing nondeterministically
on Jenkins.  The errors seem to be due to lost / missing accumulator updates, e.g.
> {code}
> Set(843, 356, 437, [...], 181, 618, 131) did not contain element 901
> {code}
> This could somehow be related to SPARK-3885 / https://github.com/apache/spark/pull/4021,
a patch to garbage-collect accumulators, which was only merged into master.
