-----------------------------------
Summary: A follower can not join the cluster for 20s seconds
Key: ZOOKEEPER-4816
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4816
Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.10.0
Reporter: gendong1
Attachments: node1.log, node2.log, node3.log
We encounter a strange scenario. When we set up the cluster of zookeeper(3
nodes totally), the third node is stuck in serializing the snapshot to the
local disk. However, the leader election is executed normally. After the
election, the third node is elected as the leader. The other two nodes fail to
connect with the leader. Hence, the first and second nodes restart the leader
election, finally the second node is elected as the leader. At this time, the
third node still act as the leader. There are two leaders in the cluster. The
first node can not join the cluster for 20s. During this procedure, the client
can not connect with any nodes of the cluster.
Runtime logs are attached.
