I am running ZooKeeper latest stable 3.8.4 release. I installed it in /usr/local/zookeeper/ and I configured /usr/local/zookeeper/conf/zoo.cfg to specify

dataDir=/var/zookeeper

The logging configuration in /usr/local/zookeeper/conf/logback.xml is

<property name="zookeeper.log.dir" value="logs" />
<property name="zookeeper.log.file" value="zookeeper.log" />

With these definitions I expected that all logs files will be in /var/zookeeper/logs.

The ZooKeeper service indeed seems to do that. However, ZK CLI does not. Running /usr/local/zookeeper/bin/zkCli.sh creates a logs directory in any directory from which it is invoked.

Is that the expected behavior?

Is that healthy that log files are not be consolidated?

After noticing that I added CLASSPATH=$CLASSPATH:/usr/local/zookeeper/conf/ but it did not change the behavior. I think that this is a requirement of LOGback.
