Is it possible to assign parameter values through Spark commands, in addition to through a user interface or a configuration file?
Spark configuration options can be defined either in a configuration file or in Spark commands.
To assign a parameter value, run the --conf command on a Spark client. The parameter value takes effect immediately after the command is run.
The command format is --conf + parameter name + parameter value. Example command:
--conf spark.eventQueue.size=50000
