[jira] [Created] (SPARK-6075) Flaky AccumulatorSuite.add value to collection accumulators test

Josh Rosen created SPARK-6075:
---------------------------------

             Summary: Flaky AccumulatorSuite.add value to collection accumulators test
                 Key: SPARK-6075
                 URL: https://issues.apache.org/jira/browse/SPARK-6075
             Project: Spark
          Issue Type: Bug
          Components: Spark Core, Tests
    Affects Versions: 1.4.0
            Reporter: Josh Rosen


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.
