-------------------------------------------
Key: JGRP-2317
URL:
https://issues.jboss.org/browse/JGRP-2317
Project: JGroups
Issue Type: Enhancement
Reporter: Bela Ban
Assignee: Bela Ban
Priority: Major
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 }}
