Let's say your dataDir and old dataLogDir is /var/lib/zookeeper and now you're moving dataLogDir to /var/lib/zookeeper-log. First you change this in the service-wide configuration, which will make the stale configuration icon appear. Then you stop zk1, ssh into zk1 and run the following commands: $ mkdir -p /var/lib/zookeeper-log/version-2 $ cp /var/lib/zookeeper/version-2/log.* /var/lib/zookeeper-log/version-2/ $ chown -R zookeeper:zookeeper /var/lib/zookeeper-log Then you can start zk1 and wait until it's running and shows as either leader or follower in the Cloudera Manager service page too. After that's done, you can do the same with zk2 and finally with zk3 too. By this point the stale configuration alert should disappear and everything should be fine cluster-wide. As you said, the log.* files need to be copied only.
