> Project: Zookeeper
> Issue Type: Bug
> Affects Versions: 3.2.0
> Reporter: Flavio Paiva Junqueira

> Fix For: 3.2.1, 3.3.0

> Attachments: ZOOKEEPER-480.patch, ZOOKEEPER-480.patch

> As a server may join leader election while others have already elected a
> leader, it is necessary that a server handles some special cases of leader
> election when notifications are from servers that are either LEADING or
> FOLLOWING. In such special cases, we check if we have received a message from
> the leader to declare a leader elected. This check does not consider the case
> that the process performing the check might be a recently elected leader, and
> consequently the check fails.
> This patch also adds a new case, which corresponds to adding a vote to
> recvset when the notification is from a process LEADING or FOLLOWING. This
> fixes the case raised in ZOOKEEPER-475.
