I am currently working on Hbase 0.90.3 and Hadoop 0.20.2 Since this hadoop version does not support rsync hdfs.. so I copied the *hadoop-core-append jar* file from *hbase/lib* folder into*hadoop folder * and replaced it with* hadoop-0.20.2-core.jar* which was suggested in the following link http://www.apacheserver.net/Using-Hadoop-bundled-in-lib-directory-HBase-at1136240.htm I guess this is what have been mentioned in the link that I am doing. If I am doing somehting wrong, kindly tell me. But now after adding that jar file.. I am not able to run my hadoop.. I am getting following exception messages on my screen ub13: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/util/PlatformName ub13: Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.util.PlatformName ub13: at java.net.URLClassLoader$1.run(URLClassLoader.java:217) ub13: at java.security.AccessController.doPrivileged(Native Method) ub13: at java.net.URLClassLoader.findClass(URLClassLoader.java:205) ub13: at java.lang.ClassLoader.loadClass(ClassLoader.java:321) ub13: at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) ub13: at java.lang.ClassLoader.loadClass(ClassLoader.java:266) ub13: Could not find the main class: org.apache.hadoop.util.PlatformName.
