在Cloudera VM中添加spark-csv包时出现问题

Question

我正在使用Cloudera quickstart VM来测试一些pyspark工作。对于一个任务，我需要添加spark-csv包。下面是我所做的：

PYSPARK_DRIVER_PYTHON=ipython pyspark -- packages com.databricks:spark-csv_2.10:1.3.0

pyspark启动得很好，但是我确实收到了警告：

**16/02/09 17:41:22 WARN util.Utils: Your hostname, quickstart.cloudera resolves to a loopback address: 127.0.0.1; using 10.0.2.15 instead (on interface eth0)
16/02/09 17:41:22 WARN util.Utils: Set SPARK_LOCAL_IP if you need to bind to another address
16/02/09 17:41:26 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable**

然后我在pyspark中运行我的代码：

yelp_df = sqlCtx.load( 
    source="com.databricks.spark.csv",  


    header = 'true',  


    inferSchema = 'true',  


    path = 'file:///directory/file.csv')

但我收到一条错误消息：

Py4JJavaError: An error occurred while calling o19.load.: java.lang.RuntimeException: Failed to load class for data source:    com.databricks.spark.csv at scala.sys.package$.error(package.scala:27)

可能出了什么问题？？提前感谢您的帮助。

尝尝这个

PYSPARK_DRIVER_PYTHON=ipython pyspark --packages com.databricks:spark-csv_2.10:1.3.0

如果没有空格，就会出现打字错误。
