             Summary: Discovery: send multiple discovery requests
                 Key: JGRP-2317
                 URL: https://issues.jboss.org/browse/JGRP-2317
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 4.0.16


Define a {{num_requests}} (default: 1) attribute (we used to have this!) that governs how many times a discovery is executed until the timeout is reached, or a coord is found.

This may be useful when multiple members are started at the same time and/or the discovery does not return the correct members the first time around. Especially needed for DNS_PING.

The number of requests should be spaced out evenly across a range [0 .. timeout-(timeout/num_requests)]

Example: timeout=12000, num_requests=3; 
* Range: [0 .. 8000] (12-4)
* First req sent at time 0
* Second: time 4000
* Third: 8000
Interval: {{timeout - (timeout/num_reqs) / num_reqs-1 }}
