使用选项(没有Spack包)启动火花放电时出错

Question

有人能告诉我为什么我会收到下面的错误吗？根据火花放电-卡桑德拉连接器的自述，下面我正在尝试的东西应该可以工作(没有星火包)：https://github.com/TargetHolding/pyspark-cassandra

$ pyspark_jar="$HOME/devel/sandbox/Learning/Spark/pyspark-cassandra/target/scala-2.10/pyspark-cassandra-assembly-0.2.2.jar"

$ pyspark_egg="$HOME/devel/sandbox/Learning/Spark/pyspark-cassandra/target/pyspark_cassandra-0.2.2-py2.7.egg"
$ pyspark --jars $pyspark_jar --py_files $pyspark_egg --conf spark.cassandra.connection.host=localhost 

这导致：

Exception in thread "main" java.lang.IllegalArgumentException: pyspark does not support any application options.

解决了问题。我需要用

--py-files 

而不是

--py_files
