In site http://wiki.apache.org/nutch/Nutch2Tutorial?action=show&redirect=GORA_HBase its said that N.B. It's possible to encounter the following exception: java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration; this is caused by the fact that sometimes the hbase TEST jar is deployed in the lib dir. To resolve this just copy the lib over from your installed HBase dir into the build lib dir. (This issue is currently in progress).
I have tried copying the HBase 0.94.8 lib in Nutch2.x/build/lib but still the same error. In my Nutch2.x/build/lib there are older versions of zookeeper and hbase and if I try to remove them from newer jars in HBase/lib then too it doesn't work. Please suggest me what else should I do.
