jahar resolved ZOOKEEPER-3070.
------------------------------
Resolution: Not A Problem
Fix Version/s: 3.4.5
Just found the way to achieve it. Was straight forward but I went into
different direction.
Below is the code:
{quote}_JMXServiceURL url = new
JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:2167/jmxrmi");_
_JMXConnector jmxConnector = JMXConnectorFactory.connect(url);_
_MBeanServerConnection mbeanServerConnection =
jmxConnector.getMBeanServerConnection();_
_ObjectName mbeanName2 = new ObjectName("log4j:logger=root");_
_System.out.println(mbeanServerConnection.getAttribute(mbeanName2,
"priority"));_
_mbeanServerConnection.setAttribute(mbeanName2, new Attribute("priority",
"DEBUG"));_

> Not Able to Change Zookeeper Logging via JMX Call

> Key: ZOOKEEPER-3070
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3070
> Project: ZooKeeper
> Issue Type: Improvement
> Components: jmx
> Affects Versions: 3.4.5
> Environment: Using Java 8 for writing standalone code to update the
> MBeans in zookeeper which is running in Windows machine for POC purpose.
> Zookeeper Version is : 3.4.5
> Reporter: jahar
> Priority: Blocker
> Fix For: 3.4.5

> Hi,
> I wanted to change the logging level of zookeeper dynamically via a JMX call
> programmatically. Apache Zookeeper official page specifies that it is
> possible to change the Mbeans via JMX calls and I have verified this through
> JConsole also.
> !zkpg.JPG!
> But the problem is that I am not able to update the Mbeans related to log4j
> through my code. I do see an API which can be used to access the Mbeans
> related to Object "org.apache.ZooKeeperService:name0=StandaloneServer_port-1"
> below is the screengrab of Jconsole and my code:
> !jconsole.JPG!
>
> Here goes my Code:
> {quote}public static void main(String[] args) throws Exception
> {
> JMXServiceURL url = new
> JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:2167/jmxrmi");
> JMXConnector jmxConnector = JMXConnectorFactory.connect(url);
> MBeanServerConnection mbeanServerConnection =
> jmxConnector.getMBeanServerConnection();
> ObjectName mbeanName = new
> ObjectName("org.apache.ZooKeeperService:name0=StandaloneServer_port-1");
> ZooKeeperServerMXBean newProxyInstance =
> MBeanServerInvocationHandler.newProxyInstance(mbeanServerConnection,
> mbeanName, ZooKeeperServerMXBean.class, true);
> System.out.println(newProxyInstance.getClientPort());
> }
> {quote}
>
>
> I dont see any API which can be used to access and update the log4J Mbeans
> e.g. "root". What I want to achieve is to update the logging of zookeeper
> without taking a restart.
> Please advice if some API is exposed to achieve this.
