Description

When trying to run the following, MAC fails to initialize Accumulo.

public static void main(String args[]){
  MiniDFSCluster dfscluster = 
    new MiniDFSCluster.Builder(new Configuration()).build();
    
  MiniAccumuloConfig macConfig = 
      new MiniAccumuloConfig(new File(args[0]), "secret");
  Map<String, String> site = new HashMap<String, String>();
  site.put("instance.volumes", dfscluster.getURI().toString() + "/accumulo");
  macConfig.setSiteConfig(site);

  MiniAccumuloCluster mac = new MiniAccumuloCluster(macConfig);
  mac.start();
}

I see the following exception in the Intialize out file

If instead of setting instance.volumes I set the following, then it works

  site.put("instance.dfs.uri", dfscluster.getURI().toString());
