Description

Following the comment here[1] I was unable to change the min.insync.replicas default value. I tested this by setting up a 3 node cluster, wrote to a topic with a replication factor of 3, using request.required.acks=-1 and setting min.insync.replicas=2 on the broker's server.properties. I then shutdown 2 brokers but I was still able to write successfully. Only after running the alter topic command setting min.insync.replicas=2 on the topic did I see write failures.
