---------------------------------------------
Summary: Py4JNetworkError: An error occurred while trying to
connect to the Java server (127.0.0.1
Key: SPARK-26047
URL: https://issues.apache.org/jira/browse/SPARK-26047
Project: Spark
Issue Type: Bug
Components: PySpark
Affects Versions: 2.4.0
Reporter: Abdul Mateen Mohammed
On IPV6, I got the following error when pyspark is invoked:
h1. Py4JNetworkError: An error occurred while trying to connect to the Java
server (127.0.0.1...)
Where as on IPV4, it is working fine.
I realized that the issue was due to default address specified as 127.0.0.1 in
java_gateway.py under py4j-0.10.7-src.zip
Resolution:
I was able to fix it by replacing the entry
DEFAULT_ADDRESS = "127.0.0.1" with DEFAULT_ADDRESS = "::1"
