SparkLauncher

Created: November-22, 2018

下面的代码是 spark 启动器的基本示例。如果必须通过某些应用程序启动 spark 作业，则可以使用此代码。

val sparkLauncher = new SparkLauncher
//Set Spark properties.only Basic ones are shown here.It will be overridden if properties are set in Main class.
sparkLauncher.setSparkHome("/path/to/SPARK_HOME")
  .setAppResource("/path/to/jar/to/be/executed")
  .setMainClass("MainClassName")
  .setMaster("MasterType like yarn or local[*]")
  .setDeployMode("set deploy mode like cluster")
  .setConf("spark.executor.cores","2")

// Lauch spark application
val sparkLauncher1 = sparkLauncher.startApplication()

//get jobId
val jobAppId = sparkLauncher1.getAppId

//Get status of job launched.THis loop will continuely show statuses like RUNNING,SUBMITED etc.
while (true) {
    println(sparkLauncher1.getState().toString)
}
