org.apache.spark.api.python.PythonUtils.getPythonAuthSocketTimeout - Ubuntu Shell/Bash

Introduction

The org.apache.spark.api.python.PythonUtils.getPythonAuthSocketTimeout function is a part of the Apache Spark framework's Python API. It is used to retrieve the timeout value for the authentication socket used by Spark drivers and executors in a Python environment on Ubuntu.

Function Signature

def getPythonAuthSocketTimeout(conf):
    """
    Retrieve the timeout value for the authentication socket used by Spark drivers and executors in a Python environment.

    Parameters:
        - conf: SparkConf - The Spark configuration object.

    Returns:
        - int - The timeout value in milliseconds.
    """

Usage Example

Here is an example of how you can use the getPythonAuthSocketTimeout function in a Ubuntu Shell/Bash script:

#!/bin/bash

# Set up Spark configuration
SPARK_HOME="/path/to/spark"
SPARK_CONF_DIR="/path/to/spark/conf"
export SPARK_HOME SPARK_CONF_DIR

# Execute Python script with specified timeout value
TIMEOUT=$(python -c "from pyspark import SparkConf; from org.apache.spark.api.python import PythonUtils; conf = SparkConf(); timeout = PythonUtils.getPythonAuthSocketTimeout(conf); print(timeout)")
echo "Python Auth Socket Timeout: $TIMEOUT ms"

# Use the timeout value in subsequent commands or scripts
# ...

Description

In a Spark cluster, the Python API allows users to interact with Spark using Python code. The getPythonAuthSocketTimeout function fetches the authentication socket timeout value from the Spark configuration object. The timeout value determines how long a driver or executor should wait for a response while establishing an authenticated communication channel.

To use this function, you need to set up the Spark configuration, including specifying the location of the Spark installation (SPARK_HOME) and the Spark configuration directory (SPARK_CONF_DIR). After that, you can execute the Python script using the python command and retrieve the timeout value by invoking PythonUtils.getPythonAuthSocketTimeout(conf).

The retrieved timeout value can then be used in subsequent commands or scripts, based on your requirements.

Note: This usage example assumes that you have already installed Apache Spark on your Ubuntu machine and have the necessary environment variables set up.
