Dear all,

I am running simple java program to create a directory in HDFS. The code as:
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.FileSystem;
import org.apache.hadoop.fs.Path;
import java.io.IOException;

public class CopyFile {

        public static void main(String[] args) throws IOException{
        Configuration conf = new Configuration();
        //conf.set("fs.default.name", "hadoop1.brunel.ac.uk:8020");
        conf.addResource(new Path("/etc/hadoop/conf/core-site.xml"));
        conf.addResource(new Path ("/etc/hadoop/conf/hdfs-site.xml"));
        FileSystem dfs = FileSystem.get(conf);
        String dirName = "Test1";
        Path src = new Path(dfs.getWorkingDirectory() + "/" + dirName);
        dfs.mkdirs(src);
        //Path scr1 = new Path("/usr/Eclipse/Output.csv");
        //Path dst = new Path(dfs.getWorkingDirectory() + "/Test1/");
        //dfs.copyFromLocalFile(scr1, dst);
        System.out.println("Directory created:" + src);
        }
        }
Generating the following error message. Anyone have any idea about this
error. Please let me know.
Exception in thread "main" java.lang.NoClassDefFoundError:

Please let me know, if anyone have any idea about the error.

This should go to one of the Hadoop User lists, not on the Flume dev list.

(But it looks like you are missing Guava in your runtime classpath, Kashif)
