Adding spark-csv package in PyCharm IDE

Question

I have successfully loaded spark-csv library in python standalone mode through

$ --packages com.databricks:spark-csv_2.10:1.4.0

Running the above command

While running the above command, it creates two folders(jars and cache) at this location

C:\Users\Mahima\.ivy2

Inside it there are two folders. One of them contains these jar files- org.apache.commons_commons-csv-1.1.jar, com.univocity_univocity-parsers-1.5.1.jar, com.databricks_spark-csv_2.10-1.4.0.jar

I want to load this library in PyCharm(Windows 10), which is already setup to run Spark programs. So I added .ivy2 folder to the Project Interpreter Path. Mainly the Error I'm getting is:

An error occurred while calling o22.load.
: java.lang.ClassNotFoundException: Failed to find data source: com.databricks.spark.csv. Please find packages at http://spark-packages.org

Full error log is as follows:

Process finished with exit code 1

I already added the jars to the project interpreter path. Where am I going wrong? Please suggest some solution. Thanks in advance

Answer 1

The solution is to add an environment variable named as "PYSPARK_SUBMIT_ARGS" and set its value to "--packages com.databricks:spark-csv_2.10:1.4.0 pyspark-shell". It will work fine.
