Hi all, I was trying to run the example from Mahout in action Chapter 7(k-Mean Clustering).Can somebody guide me how to run that example in a Hadoop Cluster(single Node CDH-4.2.1) with Mahout(0.7) These are the steps i followed: 1. Copied the code( from Github)into my Eclipse IDE, on my local machine. 2. Incuded these jars into my Eclipse project. hadoop-common-2.0.0-cdh4.2.1.jar, hadoop-hdfs-2.0.0-cdh4.2.1.jar, hadoop-mapreduce-client-core-2.0.0-cdh4.2.1.jar, mahout-core-0.7-cdh4.3.0.jar mahout-core-0.7-cdh4.3.0-job.jar, mahout-math-0.7-cdh4.3.0.jar 3. Made a Jar of this project and copied that jar onto my Hadoop Cluster 4. Executed this command user@INFPH01463U:~$ hadoop jar /home/user/apurv/Kmean.jar tryout.SimpleKMeansClustering which gave me following Error Exception in thread "main" java.lang.NoClassDefFoundError: FileSystem at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Class.java:2427) at java.lang.Class.getMethod0(Class.java:2670) at java.lang.Class.getMethod(Class.java:1603) at org.apache.hadoop.util.RunJar.main(RunJar.java:202) Caused by: java.lang.ClassNotFoundException: FileSystem at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 5 more Can anyone let me know how to add proper jars IN CDH4, I think I’m facing issues with jars. If not please can anyone let me know what I missed in this.
