我在使用 Sparkling Water 将 python 脚本作为 Spark 应用程序运行时遇到了一些麻烦。我使用这个命令在 Spark 上执行我的脚本:
./bin/spark-提交\
--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
我有这个下降的错误:
py4j.protocol.Py4JError: 试图调用一个包。

我该如何解决这个问题?我完全遵循手册中的命令:https ://h2o-release.s3.amazonaws.com/h2o/rel-turan/3/docs-website/h2o-docs/booklets/SparklingWaterVignette.pdf
