[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=12628408#comment-12628408 ] 

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

This is a good time to address ISPN-1229 cos otherwise we need to carry using regular expressions to filter things out of a stack which is ugly and could break very easily.

> 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.
> Needs further investigation
