Denis Chudov commented on IGNITE-21382:
---
The problem is that NodeUtils#transferPrimary is not competed in 30 seconds. I
would propose to rewrite this method without using
RaftGroupService#transferLeadership. Primary replica doesn't have to be
colocated with raft leader, and we can use this in tests. We have
StopLeaseProlongationMessage that is intended to stop lease prolongation for
replica which lost its ability to serve as a primary (at least, a preferred
one), and NodeUtils#transferPrimary can be reworked in a way that it sends this
message to corresponding node that is a placement driver active actor (or,
which is more simple for tests - just to every node, this message will be
ignored on other nodes).
The only problem is that StopLeaseProlongationMessage#redirectProposal is not
handled by the placement driver correctly - this is a bug and should be fixed.
After that we will obtain an ability to propose any node as the new primary and
so choose the new primary deliberately.
After that, IGNITE-20365 might be closed as well.
