Apache Toree与蟒蛇Jupyter笔记本

Question

我想寻求与Anaconda Jupyter笔记本相关的帮助。我想在Jupyter笔记本中编写PySpark和SparkR，然后我按照在线教程教授如何将Apache Toree与Jupyter笔记本一起安装。

我使用Cloudera Manager包来管理我的kerberized Hadoop集群。

但是，我无法在服务器日志中使用以下错误打开Apache Toree PySpark的内核。

我已经把jopt-simple-4.5.jar放在了Toree lib和Spark home中。是否有任何地方需要将该罐放在那里，以便在试图创建新笔记本时能够找到它？谢谢。

最好的问候， 拉赫蒂

我发现simpliest解决方案是增加下列选项火花提交：

--conf "spark.driver.extraClassPath=/usr/local/share/jupyter/kernels/apache_toree_scala/lib/toree-assembly-0.1.0-incubating.jar" --conf "spark.executor.extraClassPath=/usr/local/share/jupyter/kernels/apache_toree_scala/lib/toree-assembly-0.1.0-incubating.jar" 

这可以添加无论对/usr/local/share/jupyter/kernels/apache_toree_scala/kernel.json文件的__TOREE_SPARK_OPTS__变量或直接到/usr/local/share/jupyter/kernels/apache_toree_scala/bin/run.sh文件中的bash命令。

通过添加此操作，您可以强制类加载器从Toree JAR加载joptsimple.OptionParser而不是从默认CDH库加载。

P. S.这是一个Toree版本与CDH 5.10.0兼容：https://github.com/Myllyenko/incubator-toree/releases
