Failed to initialize sever in HandleHttpRequest Nifi

[#1]

Am trying to setup the web service using HandleHTTPRequest ->InvokeHTTP->FetchHbaseRow->HandleHTTPResponse processor. While starting the nifi process group getting the error:

[Timer-Driven Process Thread-6] o.a.n.p.standard.HandleHttpRequest org.apache.nifi.processor.exception.ProcessException: Failed to initialize the server

Any ideas on the cause. Please let me know if you need any more info..

Hi @yeah thatguy,

You would have more details about the error by looking at the log file ./logs/nifi-app.log

The most common cause is that the port you defined in the processor is already used and cannot be used by the listener started by the processor.

Hope this helps.
