Maxim Muzafarov commented on IGNITE-11803:
------------------------------------------

[~zstan]

yes, I have a plan to do this, but it's every time postpone by other activities.
Is it a critical issue? Should we raise the priority and include it, for 
example, in 2.8 Ignite release?

> Re-balancing is cancelled if client node joins, reinvestigate.
