Pyspark error: Java gateway process exited before sending its port number

pyspark gateway
install pyspark
removing the pyspark_submit_args env
spark_home = os environ get spark_home', none
pyspark gateway port
java.util.nosuchelementexception: key not found: _pyspark_driver_callback_host
pyspark_submit_args windows
export pyspark_submit_args="--master local[2] pyspark-shell"

I am using Pyspark to run some commands in Jupyter Notebook but it is throwing error. I tried solutions provided in this link (Pyspark: Exception: Java gateway process exited before sending the driver its port number) and I tried doing the solution provided here (such as Changing the path to C:Java, Uninstalling Java SDK 10 and reinstalling Java 8, still it is throwing me the same error.

I tried uninstalling and reinstalling pyspark, and I tried running from anaconda prompt as well still I am getting the same error. I am using Python 3.7 and pyspark version is 2.4.0.

If I use this code, I get this error."Exception: Java gateway process exited before sending its port number".

from pyspark import SparkContext
from pyspark.sql import SQLContext
sc = SparkContext() 
sqlContext = SQLContext(sc)
from pyspark.mllib.linalg import Vector, Vectors
from nltk.stem.wordnet import WordNetLemmatizer
from pyspark.ml.feature import RegexTokenizer, StopWordsRemover, Word2Vec

But If I remove sparkcontext from this code runs fine, but I would need spark context for my solution. Below code without spark context does not throw any error.

from pyspark import SparkContext
from pyspark.sql import SQLContext
from pyspark.mllib.linalg import Vector, Vectors
from nltk.stem.wordnet import WordNetLemmatizer
from pyspark.ml.feature import RegexTokenizer, StopWordsRemover, Word2Vec

I would appreciate if I could get any help figuring this out. I am using Windows 10 64 bit operating system.

Here is full error code picture.

Type this in you bash terminal, and it will be fixed:

export PYSPARK_SUBMIT_ARGS="--master local[2] pyspark-shell"

All this does is export pyspark-shell to the shell environment variable PYSPARK_SUBMIT_ARGS.

Java gateway process exited before sending the driver its port number, 0. it always cause python always fail when starting spark process. then spark cannot tell its ports to python. so error will be "Pyspark: Exception: Java gateway process exited before sending the driver its port number ". Pyspark: Exception: Java gateway process exited before sending the driver its port number 0 Why is a call to SparkSession.builder..getOrCreate() in python console being treated like command line spark-submit?

Try This

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Worked for me using linux.It should work for windows too

Pyspark: Exception: Java gateway process exited before sending , There is a change in python/pyspark/java_gateway.py , which requires PYSPARK_SUBMIT_ARGS that includes pyspark-shell when a PYSPARK_SUBMIT_ARGS variable is set by a user. One possible reason maybe that the JAVA_HOME is not set because java is not installed. Exception in thread "main" java. Exception: Java gateway process exited before sending the driver its port number At this code, sc = pyspark.SparkConf(). I solved it by running the code given below:

How did you install spark?? Clearly, you are having trouble starting a java process, which is what that error means.

You may want to install Spark again using the instructions to the letter, wherever you found them. However, you could also use conda, (anaconda or miniconda), in which case installing pyspark will also get a current java for you

conda install pyspark

Comments
  • Thank You @Xilpex, is this for Windows or linux ? I am using Windows 64 bit
  • @Avi this is for Linux.
  • dude!!! I went through about twenty resources and none worked until this. THANK YOU!
  • btw I have copied your answer to my question here: stackoverflow.com/a/56916343/1056563
  • btw: it is not surprising that the version without a context worked, you didn't actually try to launch anything yet.
  • I used pip install pyspark on my anaconda cmd prompt.
