[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1386) Nodes stopping can be merged without a reduced view being installed

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1386?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12628395#comment-12628395 ] 

Galder Zamarreño commented on ISPN-1386:
----------------------------------------

A very simple solution would be to leave MERGE out except in those tests that require MERGE. This shouldn't cause any issues in the testsuite because TEST_PING is deterministic in finding nodes and it's not really necessary to have MERGE as protection net for random situations in real life where nodes will only find each other after a MERGE.

> The attached log is showing a test failure because a view is not stablished with the two remaining nodes:
> {code}2011-09-14 13:01:15,124 ERROR (testng-TopologyInfoBroadcastTest) [org.infinispan.test.fwk.UnitTestTestNGListener] Method 
> testNodeLeaves(org.infinispan.distribution.topologyaware.TopologyInfoBroadcastTest) threw an exception
> java.lang.RuntimeException: Timed out before caches had complete views.  Expected 2 members in each view.  Views are as follows: 
> [[TopologyInfoBroadcastTest-NodeA-20211(s0), TopologyInfoBroadcastTest-NodeB-32215(s1), TopologyInfoBroadcastTest-NodeC-36650(s2)], 
> [TopologyInfoBroadcastTest-NodeA-20211(s0), TopologyInfoBroadcastTest-NodeB-32215(s1), TopologyInfoBroadcastTest-NodeC-36650(s2)]]
> {code}
> Having glanced some TRACE logs captured by Dan, it would appear that as NodeB is shutting down, TEST_PING finds it as a sole cluster member and finds another cluster formed of NodeA,NodeC, leading to a merge. This is somehow stopping a correct 2-node view being installed.
