This is because when zookeeper needs some time to initialise and do leader/follower election. For your case, it's just 1 cluster with 1 node. So increasing syncLimit and initLimit in zookeeper.properties should take care of the job. I would say use the following:
tickTime=1000
initLimit=5
syncLimit=10
That's a good enough delay limit.
