So in the case which you highlighted where M5 starts in a different cluster because of net issues. Now in such a case there is a possibility that if M5 tries to go in the first cluster (M1 to M4), there is an exception related to "Mismatch of hashid of M5".
So what happens when M1 receives cache.put("1",1) and M5 receieves caches.put("1",2) ? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
