Yeah I had the same problem long time ago in Pyspark in Anaconda I tried several ways to rectify this finally I found on my own by installing Java for anaconda separately afterwards there is no Py4jerror.
conda install -c cyclus java-jdk

Pyspark 2.1.0 is not compatible with python 3.6, see https://issues.apache.org/jira/browse/SPARK-19019.
You need to use earlier python version or you can try building master or 2.1 branch from github and it should work.
I am happy now because I have been having exactly the same issue with my pyspark and I found "the solution". In my case, I am running on Windows 10. After many searches via Google, I found the correct way of setting the required environment variables:
PYTHONPATH=$SPARK_HOME$\python;$SPARK_HOME$\python\lib\py4j-<version>-src.zip
The version of Py4J source package changes between the Spark versions, thus, check what you have in your Spark and change the placeholder accordingly.
For a complete reference to the process look at this site: how to install spark locally
For me
import findspark
findspark.init()
import pyspark
solved the problem
Are you using standalone spark?
Your error is : Exception: Python in worker has different version 2.7 than that in driver 3.5, PySpark cannot run with different minor versions.Please check environment variables PYSPARK_PYTHON and PYSPARK_DRIVER_PYTHON are correctly set.
Your error has been addressed here : How do I set the driver's python version in spark?
UPDATE THE SPARK ENVIRONMENT TO USE PYTHON 3.7:
Open a new terminal and type the following command: export PYSPARK_PYTHON=python3.7 This will ensure that the worker nodes use Python 3.7 (same as the Driver) and not the default Python 3.4
DEPENDING ON VERSIONS OF PYTHON YOU HAVE, YOU MAY HAVE TO DO SOME INSTALL/UPDATE ANACONDA:
(To install see: https://www.digitalocean.com/community/tutorials/how-to-install-anaconda-on-ubuntu-18-04-quickstart)
Make sure you have anaconda 4.1.0 or higher. Open a new terminal and check your conda version by typing into a new terminal:
conda --version
checking conda version
if you are below anaconda 4.1.0, type conda update conda
- Next we check to see if we have the library nb_conda_kernels by typing
conda list
Checking if we have nb_conda_kernels
- If you don’t see
nb_conda_kernelstype
conda install nb_conda_kernels
Installing nb_conda_kernels
- If you are using Python 2 and want a separate Python 3 environment please type the following
conda create -n py36 python=3.6 ipykernel
py35 is the name of the environment. You could literally name it anything you want.
Alternatively, If you are using Python 3 and want a separate Python 2 environment, you could type the following.
conda create -n py27 python=2.7 ipykernel
py27 is the name of the environment. It uses python 2.7.
- Ensure the versions of python are installed successfully and close the terminal. Open a new terminal and type
pyspark. You should see the new environments appearing.
