HTTP Source is a listener. It doesn’t actively pull from a remote endpoint.

The address in the config is an address on the flume server to bind to.

Thanks Hari

“HTTP Source does not pull anything from an address, instead it binds to the address specified
in the config”

HTTP Source does not pull anything from an address, instead it binds to the address specified
in the config. It can listen on that port and then accept data from applications.

Hi Flumers

I’m new to Flume so please go easy on me, but this is a placeholder for those that follow.

I’m seeing the following Exception when configuring a http source for Flume v1.6.0, pointing
at an externally hosted web API I know I can connect to, and GET/POST to otherwise

15/11/12 21:23:34 ERROR lifecycle.LifecycleSupervisor: Unable to start EventDrivenSourceRunner:
{ source:org.apache.flume.source.http.HTTPSource{name:<source-name>,state:IDLE} } -
Exception follows.

Here are my config lines for the Flume source:
flume-ng agent

<Flume-Agent>.sources.<source-name>.type = http
<Flume-Agent>.sources.<source-name>.port = 443
<Flume-Agent>.sources.<source-name>.bind = https://<url<https://%3curl/>
to a perfectly healthy web API> <-- serving JSON data
<Flume-Agent>.sources.<source-name>.handler = org.apache.flume.source.http.JSONHandler
<Flume-Agent>.sources.<source-name>.selector.type = replicating <-- multiple

Now I’ve seen others have had to recompile the Flume Jar to resolve this but is that really
what’s going on here?

Apart from the Exceptions, what other logging will help diagnose this?
