python - spark读入文件，报错 java.io.IOException:No input paths specified in job

Question

想尝试着处理一下文本，结果都载入不进来。。。
文件路径肯定没问题
求大神指教

fileName = "file:///Users/liuchong/Desktop/Animal Farm.txt"
liuDF = sqlContext.read.text(fileName).select('value')
print type(liuDF)
liuDF.show()

报错：

Answer 1

 No input paths specified in job

The log clearly states that the entered path does not exist.

Answer 2

Are you sure there are spaces in the middle of the text name? Animal Farm.txt"

Answer 3

Are you running in a cluster? It is recommended to throw the file into HDFS and change the path to HDFS URL.
