Hi, I'm new to the Zookeeper community. I've started using Zookeeper a few months ago.
My current goal is to build a rolling update process for three Zookeeper nodes running on AWS. During the update the virtual machines get replaced one by one. A new machine with Zookeeper is launched and added to the ensemble. Unfortunately I'm ending up with inconsistent data in Zookeeper with my current setup. Therefore I'd like to understand Zookeeper in more detail. Can somebody please point me to the answer of the following question: How to verify if a new node (follower) of the ensemble has already synchronised the current state from the leader? Is it enough to wait until SRVR returns "Mode: follower"? Or is the sync process running async? --Andreas
