Ilya Lantukh commented on IGNITE-9178:
--------------------------------------
[~agoncharuk],
I've double-checked this PR, it looks correct to me. {{leftNode2Part}} in this
case is just a temporary map that is used to fire part lost events. There is no
need to update {{diffFromAffinity}} in that part of code, because it will be
re-calculated later.

Thanks for contribution!
