Warning!!! Your instance secret is still set to the default, this is not secure. We highly recommend you change it.


You can change the instance secret in accumulo by using:
   bin/accumulo org.apache.accumulo.server.util.ChangeSecret
You will also need to edit your secret in your configuration file by adding the property instance.secret to your accumulo.properties. Without this accumulo will not operate correctly
