> The bug is due to MAPREDUCE-967 (part of hadoop 0.21 and cdh 0.20.2+737)
> 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 by setting
> 'mapreduce.job.jar.unpack.pattern' configuration to
> "(?:classes/|lib/|plugins/).*"
