使用选项启动 pyspark 时出错（没有 Spack 包）

Question

谁能告诉我为什么会出现以下错误？根据 pyspark-cassandra 连接器的 README，我在下面尝试的应该可以工作（没有 Spark 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.

找出问题所在了。我需要使用

--py-files 

代替

--py_files
