Vadim Pakhnushev updated IGNITE-19896:
--------------------------------------
Description:
When sending a message to the random node either in the refreshLeader or in the
sendWithRetry after the error, the peer to which the message was sent gets
assigned to the {{leader}} field before the message response is handled. If
during this period another thread would call {{{}leader(){}}}, it could get
random peer instead of a leader.
Also the {{leader()}} call can return incorrect result even at the time of the
{{RaftGroupEventsListener.onLeaderElected}} callback.
