I am trying to install hadoop-0.23.0-SNAPSHOT after compiling it successfully. I am getting following error while I am trying to run bin/hadoop namenode -format.
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hdfs/server/namenode/NameNode Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hdfs.server.namenode.NameNode at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: org.apache.hadoop.hdfs.server.namenode.NameNode. Program will exit. Could you help me to remove this bug? ( There is a class called namenode.class inside the given path. But it cannot identify the namenode.class ) Is there any other way to install or test new build hadoop-0.23.0-SNAPSHOT version? Is this classpath problem? if so, how to set the class path( because all .class are inside the build folder)?
