Hi Tom, Well this is strange...
No versions of hector in Nutch 2.0/runtime/deploy/nutch-2.0-dev.job or /local/lib however Gora 0.2 uses it a dependency as per /gora-cassandra/lib/hector-core0.8.0-1.jar I'm going to take some time later and try various debug combinations within eclipse to get to the bottom of this one.
