问题描述
当我尝试运行我的代码时,它会抛出异常

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
这是我的代码:
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();}}
任何想法如何解决这个问题?
Any idea how can I fix this problem?
推荐答案
问题是您在传递给 SparkConf.setMaster()的URL中指定了2个模式
。
spark
是架构,因此您无需添加 http
在 spark
之后。请参阅 <$ c的javadoc $ c> SparkConf.setMaster() 更多示例。
The spark
is the schema, so you don't need to add http
after spark
. See the javadoc of SparkConf.setMaster()
for more examples.
因此您应该使用的主URL是 火花://本地主机:18080
。更改此行:
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");
