---------------------------------
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.
