place for printing info about partition distribution

[vadopolski]

Hello guys!

I want to discuss and suggest some format and place for pinting info about
partition distribution to log from issue
https://issues.apache.org/jira/browse/IGNITE-4756

What do you think about it ?

Issue is about RendezvousAffinityFunction and FairAffinityFunction classes.

Vadim, we don't have FairAffinity any more. Can you please provide brief
and descriptive format for this message. I think we should print the
message on exchange finish before rebalancing procedure start.
