Sync of Master Master replication when Primary node comes up MySQL 5.7 Enterprise

I have a Master (say Node A) - Master (Say Node B) ***asynchronous replication*** setup with ***ROW based logging method***. Node A has been setup as Write/Read node and Node B has been setup as Read Node Only. From JBOSS , i am doing switch over that , when A node goes down , all the Write operation will get forward to B node and whenever Node A comes up , JBOSS will forward all the Writes to A node. Now suppose Node A remains down for long time , then all the Writes will go to B node . When A node comes up , it will remain un-sync for a while till it get complete sync with B . While it is getting sync , write operation is also happening on Node A which might result in locking issues as well. So my question is : Is there any method in MySQL that when Node A comes up , it will not be accessible by outer application ( like JBOSS , i have mentioned) till it gets complete sync with Node B . Can we control it via MySQL_Safe mode so that other application can perceive Node A as still down or is there any other method
