Semen Boikov updated IGNITE-999:
--------------------------------
Fix Version/s: sprint-5
> Discovery custom message can be received twice in case of IOException
> ---------------------------------------------------------------------
>
> Key: IGNITE-999
> URL: https://issues.apache.org/jira/browse/IGNITE-999
> Project: Ignite
> Issue Type: Bug
> Components: general
> Reporter: Semen Boikov
> Assignee: Yakov Zhdanov
> Priority: Blocker
> Fix For: sprint-5
>
>
> Created test DataStreamerMultinodeCreateCacheTest creating/destroying caches
> in loop. Test hangs from time to time on cache exchange, I found that this
> happens because sometimes some of nodes receive the same custom event twice
> so correct topology order becomes broken.
> Looks like problem is in the 'ServerImpl.sendMessageAcrossRing' which in
> loop tries to resend message on IOException. Issue does not reproduce if
> increase default discovery socket and ack timeout.
