[Nifi] HttpHandle Problems

[Nifi] HttpHandle Problems

New Contributor

Hi everybody,

I am new to Nifi, just try to use it almost a month.

Here is my problem with HttpHandle.

I set HttpHandle with port 20002. Everything was fine at that time and maybe later. But I see sometime, HttpHandle got die but no reason why. I tried to stop and start that processor. Here is the log.

2018-09-20 07:48:17,086 INFO [Timer-Driven Process Thread-11] org.eclipse.jetty.server.Server jetty-9.4.3.v20170317
2018-09-20 07:48:17,088 INFO [Timer-Driven Process Thread-11] o.eclipse.jetty.server.AbstractConnector Stopped ServerConnector@75f73aa6{HTTP/1.1,[http/1.1]}{}
2018-09-20 07:48:17,089 ERROR [Timer-Driven Process Thread-11] o.a.n.p.standard.HandleHttpRequest HandleHttpRequest[id=74f76727-4634-3244-5548-0a3b361ae6f3] Failed to process session due to org.apache.nifi.processor.exception.ProcessException: Failed to initialize the server: org.apache.nifi.processor.exception.ProcessException: Failed to initialize the server

Here is what I guess:

- Suddenly HTTP Processor died -> Can't receive requests but Java process still keep port 20002

- I stopped The process -> Java still keep port 20002 on

- I started The process -> Nifi can't start the processor because port 20002 was using

Any ideas?

Will you post the complete error stack from the nifi-app.log file?
