PySpark

in PySpark - pyspark shell (command line)

confs = conf.getConf().getAll()
# Same as with a spark session 
# confs = spark.sparkContext.getConf().getAll()
for conf in confs:
    print (conf[0], conf[1])

Set

Submit

The spark-submit script can pass configuration from the command line or from from a properties file

Code

In the code, see app properties

File

See below config_file

Config file

The config files (spark-defaults.conf, , spark-env.sh, log4j.properties, etc) will be searched by order of precedence at the following location

SPARK_CONF_DIR environment variable
spark_home/conf

On Linux, a redirection is used to set the conf directory to /etc/spark2/conf
