Good Morning, I am working on building nutch from source on centos to be used in conjunction with solr and hadoop.
So far I have... download the source, ( http://www.gtlib.gatech.edu/pub/apache/nutch/2.1/ ) built with ant, successfully, created a bin folder, download the nutch script, ( https://svn.apache.org/repos/asf/nutch/branches/branch-1.2/bin/nutch ) set three environmental variables: JAVA_HOME=/usr/java/jdk1.6.0_26/ NUTCH_HOME=/root/Downloads/apache-nutch-2.1/ NUTCH_JAVA_HOME=/usr/java/jdk1.6.0_26/ When attempting to run, i get the following error, [root@hdpjt01 apache-nutch-2.1]# bin/nutch crawl urls -dir crawl -depth 3 -topN 5 Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/util/PlatformName Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.util.PlatformName 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.util.PlatformName. Program will exit.

Program will exit. As I drafted this post, i see a possible problem, the script im running is from a 1.2 branch, where can I get a script for 2.1? When i attempt to run the jar directly i get other errors. I read somewhere about merging jars so it could be ran stand alone? please if someone can assist... -- View this message in context: http://lucene.472066.n3.nabble.com/building-from-src-tp4014501.html Sent from the Nutch - User mailing list archive at Nabble.com.
