Hello ; I'm trying to use Nutch and Hadoop shown here: http://wiki.apache.org/nutch/NutchHadoopTutorial
but I am using Windows 2003 ... I am trying to run this command in cygwin "bin/hadoop namenode -format" and I get the following exceptions: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/util/PlatformName Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/dfs/NameNode also I got the same exception when try to run "bin/hadoop version".. What may cause this problem? Thanks;
