Subject: How to run MIA Kmean Code.
 


 
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.
 
Thanks & Regards,
Apurv Khare
