-------------------------------------
Summary: NoSuchMethodError calling client close() in 3.4
compatibility mode
Key: CURATOR-488
URL: https://issues.apache.org/jira/browse/CURATOR-488
Project: Apache Curator
Issue Type: Bug
Components: Client
Affects Versions: TBD
Environment: Windows 7 x64
Reporter: Boris Dainson
Attachments: pom.xml
Affected version is 4.0.2-SNAPSHOT. Version 4.0.1 is not affected
When closing client it is calling zooKeeper.close(waitForShutdownTimeoutMs)
This method is only supported starting from ZK 3.5. So when running in
compatibility mode with ZK 3.4.x it throws NoSuchMethodError. So for ZK 3.4.x
need to use zooKeeper.close() with no arguments.
To reproduce:
Start ZK 3.4 server locally.
In pom.xml add dependency on zookeeper 3.4.13 and exclude default dependency
(on 3.5). Full pom.xml is attached.
Run this code snippet:
public class CloseTest {
public static void main(String[] args) throws Exception
{ CuratorFramework client =
CuratorFrameworkFactory.newClient("localhost:2181", new
ExponentialBackoffRetry(1000, 3)); client.start(); client.close(); }
}
It will throw exception:
Exception in thread "main" java.lang.NoSuchMethodError:
