Julien Nioche commented on NUTCH-1347:
--------------------------------------
Not clear what the issue is. You can group URLs into a map input by host,
domain or IP and then into each queue based on the same criteria.
BTW why not asking on the mailing list before filing a JIRA? You've opened
quite a few - which is good - but don't reply to comments or questions on them
which defeats the object
Thanks

> when Nutch is running on Hadoop , based on map-reduce concept, each map task
> do some thing on it's owned data, so, each fetcher map-task work with it's
> Queues and do not know any thing about other Queus. so, enforce delay between
> successive requests and maximum concurrent requests policies on it's Queues.
> but with a simple test we found that it's not good piliteness mechanism when
