Hi,

PySpark is Python library which is used to develop program for Apache Spark in-memory processing engine. It helps the Python programmer to quickly and easily switch on to the Spark Programming. So, if you are a Python programmer with years of experience in Python programming then it will take less than 15 days to master Spark Programming with Python (PySpark).

If you don't know Python then it will take 20 days to learn Python and then you can start PySpark programming.

Here are the steps to read a text file in Pyspark.

You have to first import the Python libraries as shown below:

from pyspark import SparkContext
from pyspark import SparkConf

After this you can use the following code to read a text file in your PySpark program:

lines = sc.textFile("/home/deepak/test1.txt")

So, its very easy to read a comma seperated file in PySpark.

You can find complete example at:

Hope above code snippet will help you in reading text file in PySpark.

Thanks
