----------------------------------------
Summary: Existing GlobalSession is not downgraded on switch to
ReadOnly
Key: ZOOKEEPER-4610
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4610
Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.7.1, 3.8.0
Reporter: Martin Güthle
Starting with
[https://github.com/apache/zookeeper/commit/c47ef905e077184bc5b7f555a3e2dfeb6dc046e1]
a ReadOnlyServer uses LearnerSessionTracker as sessionTracker. Any client
connection which have an active connection will receive or are upgraded to a
global session.
As result the client is not able to reconnect.
To avoid this, the connection should be downgraded to a local session or an
automatic reconnect should be triggered.
The solution might be to note this within the API and leave it to the client
implementation. In this case the Java CLI (called via zkCli.sh) should be
changed accordingly to take care of this behaviour.
