The "ErrorMessagesInNutch2" page has been changed by LewisJohnMcgibbney: http://wiki.apache.org/nutch/ErrorMessagesInNutch2?action=diff&rev1=4&rev2=5 == Missing plugins whilst running Nutch 2.0 on Cloudera's CDH3 == - Cloudera's CDH3 is Cloudera's distribution including Apache Hadoop. More information can be found [[https://ccp.cloudera.com/display/CDHDOC/CDH3+Quick+Start+Guide|here]]. This common error results due to a bug in MAPREDUCE-967 which modifies the way MapReduce unpacks the job's jar. The old way was to unpack the whole of it, now only classes/ and lib/ are unpacked. This way Nutch is missing the plugins/ directory. A workaround is to force unpacking of the plugin/ directory. This can be done by adding the following properties to nutch-site.xml + Cloudera's CDH3 is Cloudera's distribution including Apache Hadoop.

It is when you add the Hue distros or try to use a Hadoop installed with the Cloudera SCM products that you run into problems.
