在 Apache Storm 部署后,可以通过以下几种方式访问 JAR 文件:
import org.apache.storm.Config;
import org.apache.storm.LocalCluster;
import org.apache.storm.topology.TopologyBuilder;
public class StormTopology {
public static void main(String[] args) throws Exception {
TopologyBuilder builder = new TopologyBuilder();
// 设置 JAR 文件的本地路径
String jarPath = "/path/to/your/jar/file.jar";
Config conf = new Config();
conf.setDebug(true);
conf.put(Config.STORM_JAR, jarPath);
// 构建拓扑
// ...
// 创建本地集群并提交拓扑
LocalCluster cluster = new LocalCluster();
cluster.submitTopology("my-topology", conf, builder.createTopology());
// 等待一段时间后关闭集群
Thread.sleep(10000);
cluster.shutdown();
}
}
import org.apache.storm.Config;
import org.apache.storm.LocalCluster;
import org.apache.storm.topology.TopologyBuilder;
public class StormTopology {
public static void main(String[] args) throws Exception {
TopologyBuilder builder = new TopologyBuilder();
// 设置 JAR 文件的远程文件系统路径
String jarPath = "hdfs://localhost:9000/path/to/your/jar/file.jar";
Config conf = new Config();
conf.setDebug(true);
conf.put(Config.STORM_JAR, jarPath);
// 构建拓扑
// ...
// 创建本地集群并提交拓扑
LocalCluster cluster = new LocalCluster();
cluster.submitTopology("my-topology", conf, builder.createTopology());
// 等待一段时间后关闭集群
Thread.sleep(10000);
cluster.shutdown();
}
}
在以上示例中,jarPath
变量需要替换为实际的 JAR 文件路径。Config.STORM_JAR
属性用于指定 JAR 文件的路径,Storm 会使用该路径加载拓扑中所需的类和资源。
