Create the necessary infrastructure objects 14 | ```bash 15 | oc create -f http://radanalytics.io/resources.yaml 16 | ``` 17 | 18 | 1. Launch spring-sparkpi 19 | ```bash 20 | oc new-app --template oshinko-java-spark-build-dc \ 21 | -p APPLICATION_NAME=spring-sparkpi \ 22 | -p GIT_URI=https://github.com/radanalyticsio/spring-sparkpi \ 23 | -p APP_FILE=SparkPiBoot-0.0.1-SNAPSHOT.jar 24 | ``` 25 | 26 | 1. Expose an external route 27 | ```bash 28 | oc expose svc/spring-sparkpi 29 | ``` 30 | 31 | 1. Visit the exposed URL with your browser or other HTTP tool, for example: 32 | ```bash 33 | $ curl http://`oc get routes/spring-sparkpi --template='{{.spec.host}}'` 34 | Pi is rouuuughly 3.1335 35 | ``` 36 | -------------------------------------------------------------------------------- /pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4.0.0 4 | io.radanalytics 5 | SparkPiBoot 6 | 0.0.1-SNAPSHOT 7 | jar 8 | SparkPiBoot 9 | Demo project for Spark Pi using Spring Boot 10 | 11 | org.springframework.boot 12 | spring-boot-starter-parent 13 | 1.5.2.RELEASE 14 | 15 | 16 | 17 | 18 | UTF-8 19 | UTF-8 20 | 1.8 21 | 2.3.1 22 | 23 | 24 | 25 | org.springframework.boot 26 | spring-boot-starter-actuator 27 | 28 | 29 | org.springframework.boot 30 | spring-boot-starter-logging 31 | 32 | 33 | 34 | 35 | org.springframework.boot 36 | spring-boot-starter-web 37 | 38 | 39 | org.springframework.boot 40 | spring-boot-starter-logging 41 | 42 | 43 | 44 | 45 | org.apache.spark 46 | spark-core_2.11 47 | ${spark.version} 48 | jar 49 | 50 | 51 | 52 | 53 | 54 | org.springframework.boot 55 | spring-boot-maven-plugin 56 | 57 | ${start-class} 58 | 59 | 60 | 61 | com.coderplus.maven.plugins 62 | copy-rename-maven-plugin 63 | 1.0.1 64 | 65 | 66 | rename-file 67 | package 68 | 69 | rename 70 | 71 | 72 | target/${project.name}-${project.version}.jar.original 73 | target/${project.name}-${project.version}-original.jar 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | src/main/resources 82 | true 83 | 84 | 85 | 86 | 87 | 88 | -------------------------------------------------------------------------------- /src/main/java/io/radanalytics/SparkContextProvider.java: -------------------------------------------------------------------------------- 1 | package io.radanalytics; 2 | 3 | import org.apache.spark.SparkConf; 4 | import org.apache.spark.SparkException; 5 | import org.apache.spark.api.java.JavaSparkContext; 6 | import org.springframework.beans.factory.annotation.*; 7 | import org.springframework.stereotype.*; 8 | 9 | public class SparkContextProvider { 10 | 11 | private static SparkContextProvider INSTANCE = null; 12 | 13 | private SparkConf sparkConf; 14 | private JavaSparkContext sparkContext; 15 | 16 | private SparkContextProvider() { 17 | } 18 | 19 | private SparkContextProvider(SparkPiProperties props) { 20 | this.sparkConf = new SparkConf().setAppName("JavaSparkPi"); 21 | this.sparkConf.setJars(new String[]{props.getJarFile()}); 22 | this.sparkContext = new JavaSparkContext(sparkConf); 23 | } 24 | 25 | public static boolean init(SparkPiProperties props) { 26 | try { 27 | if (INSTANCE == null) { 28 | INSTANCE = new SparkContextProvider(props); 29 | } 30 | } catch (Exception e) { 31 | System.out.println(e.getMessage()); 32 | return false; 33 | } 34 | return true; 35 | } 36 | 37 | public static JavaSparkContext getContext() { 38 | return INSTANCE.sparkContext; 39 | } 40 | 41 | } 42 | -------------------------------------------------------------------------------- /src/main/java/io/radanalytics/SparkPiBootApplication.java: -------------------------------------------------------------------------------- 1 | package io.radanalytics; 2 | 3 | import javax.annotation.*; 4 | 5 | import org.apache.log4j.*; 6 | 7 | import org.springframework.boot.SpringApplication; 8 | import org.springframework.boot.autoconfigure.SpringBootApplication; 9 | import org.springframework.beans.factory.annotation.Autowired; 10 | 11 | @SpringBootApplication 12 | public class SparkPiBootApplication { 13 | 14 | private static final Logger log = Logger.getRootLogger(); 15 | 16 | @Autowired 17 | private SparkPiProperties properties; 18 | 19 | @PostConstruct 20 | public void init() { 21 | log.info("SparkPi submit jar is: "+properties.getJarFile()); 22 | if (!SparkContextProvider.init(properties)) { 23 | // masterURL probably not set, 24 | // meaning this was likely run outside of oshinko 25 | System.exit(1); 26 | } 27 | } 28 | 29 | public static void main(String[] args) { 30 | SpringApplication.run(SparkPiBootApplication.class, args); 31 | } 32 | 33 | } 34 | -------------------------------------------------------------------------------- /src/main/java/io/radanalytics/SparkPiController.java: -------------------------------------------------------------------------------- 1 | package io.radanalytics; 2 | 3 | import org.springframework.web.bind.annotation.RestController; 4 | import org.springframework.web.bind.annotation.RequestMapping; 5 | import org.springframework.web.bind.annotation.RequestParam; 6 | 7 | @RestController 8 | public class SparkPiController { 9 | 10 | @RequestMapping("/") 11 | public String index() { 12 | return "Java Spring Boot SparkPi server running.
