> in NutchJob and NutchTool, the job starts without errors.
> Notes:
> - the job this error was observed a [custom de-duplication
> job|https://github.com/commoncrawl/nutch/blob/cc/src/java/org/apache/nutch/crawl/DedupRedirectsJob.java]
> to flag redirects pointing to the same target URL. But I'll try to reproduce
> it with a standard Nutch job and in pseudo-distributed mode.
> - should also verify whether registering URL stream handlers works at all in
> distributed mode. Tasks are launched differently, not as NutchJob or
> NutchTool.
