Yep also check out the work that Sujen Shah just merged (also on my team at JPL and USC) where you can publish events to an ActiveMQ queue from Nutch crawling. That should allow all sorts of production dashboards and analytics.

I have created a prototype for production queue [0] which runs on top of a supercomputer (TACC Wrangler) and integrated it with Kafka. Please have a look and let me know if you have any questions.

I am just giving one. :) Regards, Karanjeet Singh http://irds.usc.edu On Thu, Sep 29, 2016 at 1:33 AM, Sachin Shaju <[email protected]> wrote: > Hi, > I was experimenting some crawl cycles with nutch and would like to setup > a distributed crawl environment.
