Note: copy the specified folder from inside the zip files and make sure you have environment variables set right as mentioned in the beginning.Ĭopy the py4j folder from : C:\apps\opt\spark-3.0.0-bin-hadoop2.7\python\lib\py4j-0.10.9-src.zip\
Sometimes after changing/upgrading Spark version, you may get this error due to version incompatible between pyspark version and pyspark available at anaconda lib. Copying the pyspark and py4j modules to Anaconda lib # you can also pass spark home path to init() method like below
#PYCHARM PROFILER INSTALL#
Install findspark package by running $pip install findspark and add the following lines to your pyspark program import findspark PATH => %SPARK_HOME%/bin %SPARK_HOME%/python %PATH%Īfter setting the environment variables, restart your tool or command prompt. PYTHONPATH => %SPARK_HOME%/python %SPARK_HOME%/python/lib/py4j-0.10.9-src.zip %PYTHONPATH% If you are running on windows, open the environment variables window, and add/update below. export SPARK_HOME=/opt/spark-3.0.0-bin-hadoop2.7Įxport PYTHONPATH=$SPARK_HOME/python:$SPARK_HOME/python/lib/py4j-0.10.9-src.zip:$PYTHONPATHĮxport PATH=$SPARK_HOME/bin:$SPARK_HOME/python:$PATH Note: Do not copy and paste the below line as your Spark version might be different from the one mentioned below. For Unix and Mac, the variable should be something like below.
