Nifi Demo Installation through Ambari failed

[#1]

I have installed HDP 2.6.3 and its working fine.Now i want to add Nifi through Actions--> Add service option in Ambari . But after installation its showing "failed installation". During installation there were approximately 16 recommended config changes. I tried to modify as per the recommendations but again some other service conflicts are arising. What should i do now? Any help is greatly appreciated. Thank you.nifi-installation-failed.jpgnifi-demo.jpg
