>                 Key: ZOOKEEPER-3489
>                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3489
>             Project: ZooKeeper
>          Issue Type: Bug
>          Components: java client, security
>         Environment: 	Ubuntu 16.04.3 LTS
> 	Open JDK version "1.8.0_191" build 25.191-b12
>            Reporter: xiaoqin.fu
>            Priority: Major
>
>    In org.apache.zookeeper.ClientCnxn$SendThread, statements LOG.warn(....) don't have
LOG configuration controls.	
>         void readResponse(ByteBuffer incomingBuffer) throws IOException {
>             ......
> 			LOG.warn("Got server path " + event.getPath()
> 					+ " which is too short for chroot path "
> 					+ chrootPath);
> 			......					
>         }
> 	Sensitive information about event path and chroot path may be leaked. The LOG.isWarnEnabled()
conditional statement should be added:
> 	    void readResponse(ByteBuffer incomingBuffer) throws IOException {
>             ......
> 			if (LOG.isWarnEnabled())
> 				LOG.warn("Got server path " + event.getPath()
> 					+ " which is too short for chroot path "
> 					+ chrootPath);
> 			......					
>         }
