I ran into the same problem today. Found a solution that works: bin/hadoop jar -libjars <comma separated jars> hadoop-xxx-index.jar -inputPaths...
E.g., in your particular case, you command will look like: bin/hadoop jar -libjars lib/lucene-core-2.3.1.jar contrib/index/hadoop-0.17.1-index.jar -inputPaths src/contrib/index/sample -outputPath index-msg-out -indexPath index -conf src/contrib/index/conf/index-config.xml Kyle On Fri, 2008-10-10 at 16:35 +0800, chenlbspace wrote: > hi, > > I try to use contrib/index/hadoop-0.17.1-index.jar build lucene index, but > Directory NoClassDefFoundError. > > How solve?
