Я не могу выполнить приведенный ниже код.Этот код пытался выполнить запрос улья из таблицы улья, используя SparkSession внутри метода runjob () SparkContext.
val lines = sparkSession.sparkContext.parallelize(Seq("hello world"),1)
sparkSession.sparkContext.runJob(lines, (t: TaskContext, it: Iterator[String]) => {
val conf = new SparkConf().setAppName("Testing")
val session = SparkSession.builder().master("local[*]").config(conf).enableHiveSupport().getOrCreate()
var df : DataFrame= session.sql(s"select count(*) from employee")
println("Task attempt id => " + t.taskAttemptId() + " and count:" + df.first)
})
I am able to get the result in local IntelliJ. However when I try to run the JAR in "yarn cluster" mode, I am getting the below exception:-
