[jboss-jira] [JBoss JIRA] (JGRP-2317) Discovery: send multiple discovery requests

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 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 }}
