Environment variables can be used to set per-machine settings, such as the IP address, through the conf/spark-env.sh script on each node. It is also sourced when running local Spark applications or submission scripts. Using WebSockets and Spark to create a real-time chat app; Deploying Spark on Heroku; Setting up Spark with Maven; Setting up Spark with Maven. The default location of the Spark configuration files depends on the type of installation: Package installations and Installer-Services: /etc/dse/spark/ Tarball installations and Installer-No Services: installation_location /resources/spark/conf Configuration Files are the files which are located in the extracted tar.gz file in the etc/hadoop/ directory. Logging can be configured through log4j.properties. Environment variables can be used to set per-machine settings, such as the IP address, through the conf/spark-env.sh script on each node.

Spark provides three locations to configure the system: Spark properties control most application parameters and can be set by using a SparkConf object, or through Java system properties. Certain Spark settings can be configured through environment variables, which are read from the conf/spark-env.sh script in the directory where Spark is installed (or conf/spark-env.cmd on Windows). In Standalone and Mesos modes, this file can give machine specific information such as hostnames. 2. 3. Logging can be configured through log4j.properties. They could also be set using Java system properties if you are programming in a language runnable on JVM. All Configuration Files in Hadoop are listed below, 1) HADOOP-ENV.sh->>It specifies the environment variables that affect the JDK used by Hadoop Daemon (bin/hadoop).We know that Hadoop framework is wriiten in Java and uses JRE so one of the environment variable in Hadoop … Spark Application Parameters could be setup in the spark application itself using SparkConf object in the Driver program. Spark Configuration Spark provides three main locations to configure the system: Environment variables for launching Spark workers, which can be set either in your driver program or in the conf/spark-env.sh script.
