title: Is it possible to replicate kafka topics without alias prefix with MirrorMaker2
body: <p>I'm trying to set up replication between 2 clusters but don't want want the topic names to be changed. for example if i have a topic called "some_topic" it is automatically replicated to "cluster1.some_topic", I'm pretty sure this can be done but haven't found the correct config to change this</p>
  
  <p>My current config "mirrormaker2.properties"</p>
  
  <pre><code># Sample MirrorMaker 2.0 top-level configuration file
  # Run with ./bin/connect-mirror-maker.sh connect-mirror-maker.properties 
  
  # specify any number of cluster aliases
  clusters = cluster1, cluster2
  
  # connection information for each cluster
  cluster1.bootstrap.servers = host1:9092,host2:9092,host3:9092
  cluster2.bootstrap.servers = rep_host1:9092,rep_host2:9092,rep_host3:9092
  
  # enable and configure individual replication flows
  cluster1-&gt;cluster2.enabled = true
  cluster1-&gt;cluster2.topics = sometopic.*
  
  # customize as needed
  # replication.policy.separator = _
  # sync.topic.acls.enabled = false
  # emit.heartbeats.interval.seconds = 5
  </code></pre>
