ListenHTTP processor
Hi,
I am getting an error as 'failed to invoke @OnSchedule method due to
java.net.SocketException:Permission denied' when using 'ListenHTTP
processor'.
Please suggest how to resolve the issue.
Thanks & Regards,
Sudeep Shekhar Mishra

Thanks Jeremy.
I was running NiFi with another user account and not as a root user.
Running NiFi as a root user helped to resolve the issue.

Sudeep,
ListenHTTP tries to bind to port 80 by default which is a privileged port. All ports 1024 and below are privileged ports and must be opened by root. Try setting the port number on ListenHTTP to something higher than 1024

NiFi only needs to be running as root if you are trying to use ports 1024
or below. Ports above 1024 do not require privileged access on Linux. Try
using port 8081 instead for your listenHTTP processor. This will allow you
to run your NiFi as a non root user.

Thanks Joe.
One doubt though... maybe some Linux changes required but do I have to run
NiFi as root user only to make use of ListenHTTP processor?

Hello
Sounds like you're on track now. Just wanted to correct one comment made
ListenHTTP by default does not set an input port and instead it is a
required input.
Thanks
Joe

Hi Sudeep,
On which port are you listening ?
Also which OS are you using ?
