Spark Groovy

Sandbox testing Groovy based Spark applications

Quickstart

Download and unzip Spark in a directory of your choice, then set the SPARK_HOME directory.

Clone this repo:

git clone https://github.com/pditommaso/spark-groovy.git
cd spark-groovy

Compile the examples:

./gradlew jar

Launch the GroovyWordCount:

$SPARK_HOME/bin/spark-submit \
  --class "org.apache.spark.examples.GroovyWordCount" \
  build/libs/gspark-1.0.jar 
  README.md

Deploy jobs on a local cluster

Launch the Spark master:

$SPARK_HOME/sbin/start-master.sh

Launch a Spark worker:

$SPARK_HOME/sbin/start-slave.sh spark://$HOSTNAME:7077 -c 1 -m 1G

Run the Groovy PI example:

$SPARK_HOME/bin/spark-submit \
  --class org.apache.spark.examples.GroovySparkPi \
  --master spark://$HOSTNAME:7077 \
  build/libs/gspark-1.0.jar

Check the Spark daskbord opening the browser at the address http://localhost:8080/

Stop master and slave instances:

$SPARK_HOME/sbin/stop-slave.sh && $SPARK_HOME/sbin/stop-master.sh

Deploy Ignite application over a Spark cluster

Compile the project:

./gradlew shadowJar

Launch the Ignite example:

$SPARK_HOME/bin/spark-submit \
    --class org.apache.ignite.examples.GroovyIgniteSimpleApp \
    --master spark://$HOSTNAME:7077 \
    build/libs/gspark-1.0-all.jar
