Consistency check failed on Ambari when add nifi service

[#1]

I add nifi on ambari UI. In the step 6,I see the following message.

Consistency check failed

The configuration changes could not be validated for consistency due to an unknown error. Your changes have not been saved yet. Would you like to proceed and save the changes?

In the browser(chrome console), i get this warning message(i do not know whether it leads to the check failed):

historyserver_host from mapreduce2-site.xml can't be validate

zookeeper_server_hosts from zookeeper-site.xml can't be validate

kafka_broker_hosts from kafka-site.xml can't be validate

ps:there is no mapreduce2-site.xml/zookeeper-site.xml/kafka-site.xml in my ambari server host

and the code may be in app.js

buildConfigsJSON: function(services, stepConfigs)

    .............
          if (configurations[property.get('filename').replace('.xml','')]){
            configurations[property.get('filename').replace('.xml','')]['properties'][property.get('name')] = property.get('value');
          } else {
            console.warn(property.get('name') + " from " + property.get('filename') + " can't be validate");
          }
        });

if i hit processed anyway. the nifi can be installed correctly.

But i do not want to get the step6 error when add service. How to solve it?

Apache Nifi and Ambari integration is not complete yet, therefore you get errors. You need to wait for official release.
