> Key: IGNITE-6604
> URL: https://issues.apache.org/jira/browse/IGNITE-6604
> Project: Ignite
> Issue Type: Improvement
> Components: general
> Affects Versions: 2.1
> Reporter: Alexander Belyak
> Priority: Minor
>
> Sometimes exchange process hangs (because some errors, OOMe, deadlocks, etc),
> sometimes it require significant time to finish (finish eviction, long Full
> GC, etc).
> We need some logging, that will show progress, because often exchange is
> block whole cluster and support team wanna know what's happen and how many
> time it will continue. Main point - simplify throubleshooting, just as grep
> standard message/logging class, for example: "Exchange progress: evicting
> partition <partId>" or "Exchange progress: waiting for response from <N>
> nodes".
