Resolution: Duplicate
> pyspark - class loading on driver failing with --jars and --packages
> --------------------------------------------------------------------
>
> Key: SPARK-6047
> URL: https://issues.apache.org/jira/browse/SPARK-6047
> Project: Spark
> Issue Type: Bug
> Components: PySpark, Spark Submit
> Affects Versions: 1.3.0
> Reporter: Burak Yavuz
>
> Because py4j uses the system ClassLoader instead of the contextClassLoader of the thread, the dynamically added jars in Spark Submit can't be loaded in the driver.
> This causes `Py4JError: Trying to call a package` errors.
> Usually `--packages` are downloaded from some remote repo before runtime, adding them explicitly to `--driver-class-path` is not an option, like we can do with `--jars`. One solution is to move the fetching of `--packages` to the SparkSubmitDriverBootstrapper, and add it to the driver class-path there.
> A more complete solution can be achieved through [SPARK-4924].
