> Key: SPARK-20080
> URL: https://issues.apache.org/jira/browse/SPARK-20080
> Project: Spark
> Issue Type: Bug
> Components: DStreams
> Affects Versions: 2.1.0
> Environment: local spark and yarn from big top 1.1.0 version
> Reporter: Nick Hryhoriev
> Priority: Minor
>
> When i try use or init org.slf4j.Logger inside foreachPartition, that
> extracted to trait method.
> What was called in foreachRDD.
> I have found that foreachPartition method do not execute and no exception
> appeared.
> Tested on local and yarn mode spark.
> code can be found on
> [github|https://github.com/GrigorievNick/Spark2_1TraitLoggerSerialisationBug/tree/9da55393850df9fe19f5ff3e63b47ec2d1f67e17].
> There are two main class that explain problem.
> if i will run same code with batch job. I will get right exception.
