Hi Andrew,
As that "Caused by" error notes, it appears that Solr cannot find your
statistics data in the "/www/dspace/solr/statistics/data/" folder (and the
subfolders under that).
Are you certain you have statistics data in that specific location on your
filesystem? Are you sure that Solr is up and running while you try to do
the export?
You also might want to check Solr's own logs, as it's possible more
detailed information is available there. It could be a simple permissions
issue, or a configuration issue, or any number of other things.
Good luck,
Tim
