Hi Yuliya, The masted id is used to resolve conflicts when 2 servers have the latest transaction id during leader election. Also, its used as the first N bits for the session id to make it unique across zookeeper servers.

My suggested answer is that it won't hurt anything, but it may cause that node to discard any snapshots or logs created under the old id. Anybody have corrections or amplifications to this?
