./sbin/start-master.shManagement Scripts for Standalone Master
You can start a Spark Standalone master (aka standalone Master) using sbin/start-master.sh and stop it using sbin/stop-master.sh.
sbin/start-master.sh
sbin/start-master.sh script starts a Spark master on the machine the script is executed on.
The script prepares the command line to start the class org.apache.spark.deploy.master.Master and by default runs as follows:
org.apache.spark.deploy.master.Master \
--ip japila.local --port 7077 --webui-port 8080|
Note
|
The command sets SPARK_PRINT_LAUNCH_COMMAND environment variable to print out the launch command to standard error output. Refer to Print Launch Command of Spark Scripts.

It has support for starting Tachyon using --with-tachyon command line option. It assumes tachyon/bin/tachyon command be available in Spark’s home directory.
The script uses the following helper scripts:
-
sbin/spark-config.sh -
bin/load-spark-env.sh -
conf/spark-env.shcontains environment variables of a Spark executable.
Ultimately, the script calls sbin/spark-daemon.sh start to kick off org.apache.spark.deploy.master.Master with parameter 1 and --ip, --port, and --webui-port command-line options.
