[infinispan-issues] [JBoss JIRA] (ISPN-2357) New coordinator installs old CH containing crashed members

[Erik Salter (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12722690#comment-12722690 ] 

Erik Salter commented on ISPN-2357:
-----------------------------------

After looking at the trace logs, it looks like the coordinator dying abruptly fails to send a LEAVE ClusterControlCommand, so the first thing the new coordinator does is do a GET_STATUS without consulting the view it received.

Maybe the first thing the new coordinator should do is ask the nodes to reconcile their current views with the views received from JGroupsTransport?

> After merging the round of pull requests today (including ISPN-2349), there still is an issue where a killed node can appear in the CH even after JGroups passes up the new view.  This appears to happen when the old coordinator was killed.
> Obviously, if the CH contains the old member, writes that map to the segments previously owned by the dead node will fail.
