когда я запускаю свое веб-приложение, я получаю эту ошибку, я хочу получить некоторые данные из mongodb с помощью spark и выполнить некоторые spark-sql, например, код:
я вернул пустой список, потому что я тестировал, ноэто не должно приводить к ошибке из-за того, что проблема в том, что когда я заполняю набор данных mongospark.
я использовал фляги из папки spark, поэтому я не думаю, что у меня проблема с библиотеками, и я уже пробовал это в java-приложениии это работает
public List<temp> test(){
List<temp> listtmp = new ArrayList<>();
SparkSession spark = SparkSession.builder()
.master("spark://192.168.1.103:7077")
.appName("MongoSparkConnectorIntro")
.config("spark.mongodb.input.uri", "mongodb://127.0.0.1/temperature.templog")
.config("spark.mongodb.output.uri", "mongodb://127.0.0.1/temperature.templog")
.getOrCreate();
// Create a JavaSparkContext using the SparkSession's SparkContext object
JavaSparkContext jsc = new JavaSparkContext(spark.sparkContext());
/*Start Example: Read data from MongoDB************************/
Dataset<Row> df = MongoSpark.load(jsc).toDF();
/*End Example**************************************************/
df.createOrReplaceTempView("temp");
Dataset<Row> data = spark.sql("select * from temp");
// Analyze data from MongoDB
return listtmp;
}
