Apache Spark reassigned SPARK-13344:
------------------------------------
Assignee: Apache Spark (was: Andrew Or)
> SaveLoadSuite has many accumulator exceptions
> ---------------------------------------------
>
> Key: SPARK-13344
> URL: https://issues.apache.org/jira/browse/SPARK-13344
> Project: Spark
> Issue Type: Bug
> Components: SQL, Tests
> Affects Versions: 2.0.0
> Reporter: Andrew Or
> Assignee: Apache Spark
>
> This is because SparkFunSuite clears all accumulators after every single
> test. This suite reuses a DF and all of its associated internal accumulators
> across many tests.
> This is likely caused by SPARK-10620.
