[JBoss JIRA] (JGRP-2293) Graceful concurrent leaving of coordinator(s) leaves the cluster with stale views
by Dan Berindei (Jira)
[ https://issues.jboss.org/browse/JGRP-2293?page=com.atlassian.jira.plugin.... ]
Dan Berindei commented on JGRP-2293:
------------------------------------
[~belaban] I ran our test suite a few times without reproducing the failure. Then I got the idea to repeat the offending test 100 times, and I got it to fail both with JGroups 4.0.15.Final and with 4.0.17-SNAPSHOT. Finally I analyzed the logs and I think it is a problem with the test itself, so the fix is good for me.
I still haven't managed to run {{LeaveTest}} successfully from the command line though, the nodes never form a cluster because they don't see each other's MPING requests. If I run without {{<jvmarg value="-Djava.net.preferIPv4Stack=true"/>}} I get a sendto error (see below), but with it I get no error message, the nodes just don't see each other. I'd say it's a problem with my environment, but the same test using the same mcast address (230.0.5.6.7) passes when run from the IDE.

> JGroups does not handle concurrent leaving of nodes correctly. This is a typical use case in cloud environment when scaled down with an autoscaler/manually which we need to handle.
> A simple test can be devised which fails first n (where n>1) nodes from a cluster, reproducer PR https://github.com/belaban/JGroups/pull/397

> Currently there are several areas in UI tests that do not have call to Openshift API for data comparison.
> 1. Figure out which calls are missing to Openshift.
> 2. Create API call.
> 3. Create assertions on that results to compare with UI data.
> 4. PR per area (API call).
