Pyspark SQL Error

Hi,

I am running the following lines under PySpark 2.0 console and getting the following error. I am not sure if i am missing any config setting.

Code:
from pyspark.sql import SparkSession
spark.read.option(“header”, “true”).csv("/home/senthiljdpm7608/PySpark/RealEstate.csv")

Error:
py4j.protocol.Py4JJavaError: An error occurred while calling o132.csv.
: java.lang.RuntimeException: Multiple sources found for csv (org.apache.spark.sql.execution.datasources.csv.CSVFileFormat, com.databricks.spark.csv.DefaultSource15), please specify the fully qualified class name.

Can you please give me a hint how to resolve this?
