[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1091) HotRod clients should failover if encountering a SuspectException

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12602157#comment-12602157 ] 

Galder Zamarreño commented on ISPN-1091:
----------------------------------------

I have my doubts about dealing in the same way with timeout or repl timeout exceptions. A suspect exception is a clear thing cos you want to repeat the operation cos the node was suspected and so it's no longer part of the cluster. But for timeouts, any retry would make sense with a back-off of some sort to avoid too many lock acquisition contention. For the moment I'm gonna leave this out and focus on what needs fixing immediately which is the suspect exception.

> As Michal rightly indicated in JBPAPP-6473, Hot Rod clients need to be able to deal with SuspectException errors and failover rather than bubbling up. In the future the server will make sure the right error code is returned, but in the absence of that, the error message can be inspected.
