--------------------------------------
Summary: ReadOnlyRequestProcessor doesn‘t filter closeSession
and createSession
Key: ZOOKEEPER-4388
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4388
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.6.2, 3.6.1, 3.6.3, 3.6.0
Environment: zk version 3.6.0 3.6.1 3.6.2
the follower/observer network disconnection time exceeds session timeout
Reporter: shixiaoxiao
Fix For: 3.7
Attachments: dataInconsistent.png
The follower/observer enable read only. When the node returns to normal from
the partitioned, the ephemerals nodes will be inconsistent with the leader
node. The reason is that the request to close the timeout sessions is processed
by the ReadOnly follower or observer when they are partitioned and the
ephemerals nodes created by these sessions also are delete. When the leader
node uses diff to synchronize data with the follower/observer node, the
transaction that needs to be synchronized does not include the creation of
temporary nodes which created by sessions closed by followers.So the
follower/observer ephemerals nodes is inconsistent with leader.
