> DStream.saveAsHadoopFiles can throw ConcurrentModificationException
> -------------------------------------------------------------------
>
> Key: SPARK-12087
> URL: https://issues.apache.org/jira/browse/SPARK-12087
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.3.1, 1.4.1, 1.5.2
> Reporter: Tathagata Das
> Assignee: Tathagata Das
>
> The JobConf object created in DStream.saveAsHadoopFiles is used concurrently
> in multiple places:
> - The JobConf is updated by RDD.saveAsHadoopFile() before the job is launched
> - The JobConf is serialized as part of the DStream checkpoints.
> These concurrent accesses (updating in one thread, while the another thread
> is serializing it) can lead to concurrentModidicationException in the
> underlying Java hashmap using in the internal Hadoop Configuration object.
