When I'm trying to run my code it throws this Exception
:
Exception in thread "main" org.apache.spark.SparkException: Could not parse Master URL:spark:http://localhost:18080
This is my code:
SparkConf conf = new SparkConf().setAppName("App_Name").setMaster("spark:http://localhost:18080").set("spark.ui.port","18080");
JavaStreamingContext ssc = new JavaStreamingContext(sc, new Duration(1000));
String[] filet=new String[]{"Obama","ISI"};
JavaReceiverInputDStream<Status> reciverStream=TwitterUtils.createStream(ssc,filet);
JavaDStream<String> statuses = reciverStream.map(new Function<Status, String>() {
public String call(Status status) { return status.getText(); }
}
);
ssc.start();
ssc.awaitTermination();}}
Any idea how can I fix this problem?
The problem is that you specify 2 schemas in the URL you pass to SparkConf.setMaster()
.
The spark
is the schema, so you don't need to add http
after spark
. See the javadoc of SparkConf.setMaster()
for more examples.
So the master URL you should be using is "spark://localhost:18080"
. Change this line:
SparkConf conf = new SparkConf().setAppName("App_Name")
.setMaster("spark://localhost:18080").set("spark.ui.port","18080");
