INFO [Thread-1] org.apache.nifi.NiFi Jetty web server shutdown completed (nicely or otherwise).

NOTE :I already tried this following configuration.

1. My java path is correct

2.etc/hosts are also correct

3.nifi.properties http.port is 8090

I installed NIFI without Ambari in centos but, I am using Ambari on the same server already

I did wget <repo>from apache NIFI and extracted in to the /usr/src/ folder

There are two separate processes that are associated to Nifi on startup.

The bootstrap service starts and listens for requests from the second nifi process (main application). The Exception above leads me to believe that the second process is unable to communicate with the bootstrap process listening on port 24264. This is likely because it is trying to communicate with localhost:24264 and you so not have an entry in your server's /etc/hosts file resolving localhost to any address (for example: 127.0.0.1 localhost)

Thank you,

You are also going to want to make sure you have set the following nifi.properties file properties:

nifi.web.http(s).host= leaving this blanks means Java will try to determine hostname which may result in an incorrect hostname being determined or Java just using localhost instead of the actual server hostname.
-

Then you want to make sure whatever hostname you enter here is properly resolvable to a valid IP for your server.

Hi,

I already metioned nifi.web.http(s).host=(my server ip) in nifi.properties. But problem still remains same. I mentioned my IP insteead of my FQDN.

[#5]

i am running NiFi on ambari server, at the starting time i am getting this error. As per your response, which file port or what to be changed in system. Bcz i did not understand your answer. And in my /etc/hosts i configured 4 host server ip with FQDN I am running NiFi only one Host and so how it can communicate to another process(main application) where to find out second NiFi process in ambari. I downloaded NiFi-1.6.0 on 1 host and it was configured.
