You shouldn't end up in this mixed-version situation at all. I would highly recommend you upgrade all the nodes to 3.11.5 or whatever the latest version is installed on the nodes. Mixed-versions isn't a tested or supported scenario and the cluster's behaviour can be unpredictable. The behaviour might not be catastrophic but you don't want to be the one who discovers some exotic bug that arises out of that configuration. Cheers! >
