Sparkling Water - 运行 python 脚本作为 Spark 应用程序

Question

我在将 Sparkling Water 运行 python 脚本作为 Spark 应用程序时遇到了一些问题。我使用此命令在 Spark 上执行我的脚本：

./bin/spark-submit \

--packages ai.h2o:sparkling-water-core_2.10:1.5.12 \

--py-files $SPARKLING_HOME/py/dist/pySparkling-1.5.12-py2.7.egg $SPARKLING_HOME/Python/test.py

我有这个坠落错误：

py4j.protocol.Py4JError: Trying to call a package.

日志：

我该如何解决这个问题？我完全按照手册中的命令进行操作：https://h2o-release.s3.amazonaws.com/h2o/rel-turan/3/docs-website/h2o-docs/booklets/SparklingWaterVignette.pdf
