The above step will launch and run the image with:

  • root is the user we logged into.
  • spark is the container name.
  • spark is host name of this container.
    • This is very important as Spark Slaves are started using this host name as the master.
  • The container exposes ports 4040, 8080, 8081 for Spark Web UI console(s).

Check softwares and versions

Spark commands

All the required binaries have been added to the PATH.

Start Spark Master

start-master.sh

Start Spark Slave

start-slave.sh spark://spark:7077

Execute Spark job for calculating Pi Value

spark-submit --class org.apache.spark.examples.SparkPi --master spark://spark:7077 $SPARK_HOME/examples/jars/spark-examples*.jar 100
.......
.......
Pi is roughly 3.140495114049511

OR even simpler

$SPARK_HOME/bin/run-example SparkPi 100
.......
.......
Pi is roughly 3.1413855141385514

Please note the first command above expects Spark Master and Slave to be running. And we can even check the Spark Web UI after executing this command. But with the second command, this is not possible.

Start Spark Shell

spark-shell --master spark://spark:7077

View Spark Master WebUI console
