"No FileSystem for scheme: hdfs" when submitting a remote job
Hi,
I am trying to submit a remote mapreduce job in Yarn with the
configuration below, but I get the error |No FileSystem for scheme:
hdfs|. The error is so also below. Why this is happening?
| String host = "192.168.56.100";
Configuration conf = job.getConfiguration();
// this should be like defined in your yarn-site.xml
conf.set("yarn.resourcemanager.address", host + ":50001");
// framework is now "yarn", should be defined like this in mapred-site.xm
conf.set("mapreduce.framework.name", "yarn");
// like defined in hdfs-site.xml
conf.set("fs.defaultFS", "hdfs://" + host + ":9000");
for (Path inputPath : inputPaths)
FileInputFormat.addInputPath(job, new Path(conf.get("fs.defaultFS") + "/" + inputPath.toString()));
FileOutputFormat.setOutputPath(job, new Path(conf.get("fs.defaultFS") + "/" + tempPath));
job.waitForCompletion(true);

Yes, this was the problem. But I have another question:
When I am starting a remote job, the job will run in the remote resource manager. But how the job that is running remotely will know where are the map and reduce functions?

Have you added hadoop-hdfs-xxxx.jar into your class path ?

Subject: "No FileSystem for scheme: hdfs" when submitting a remote job
Hi,
I am trying to submit a remote mapreduce job in Yarn with the configuration below, but I get the error No FileSystem for scheme: hdfs. The error is so also below. Why this is happening?
String host = "192.168.56.100";
Configuration conf = job.getConfiguration();
// this should be like defined in your yarn-site.xml
conf.set("yarn.resourcemanager.address", host + ":50001");
// framework is now "yarn", should be defined like this in mapred-site.xm
conf.set("mapreduce.framework.name", "yarn");
// like defined in hdfs-site.xml
conf.set("fs.defaultFS", "hdfs://" + host + ":9000");
for (Path inputPath : inputPaths)
FileInputFormat.addInputPath(job, new Path(conf.get("fs.defaultFS") + "/" + inputPath.toString()));
FileOutputFormat.setOutputPath(job, new Path(conf.get("fs.defaultFS") + "/" + tempPath));
job.waitForCompletion(true);
Exception in thread "main" java.io.IOException: No FileSystem for scheme: hdfs
