telnet connection refused

[#1]

I was learning flume agent. my flume agent was listening to localhost and port 2222. I was able to telnet successfully and see the logs captured by flume agent.

Suddently I noticed, some messages (jobs stopped. Reset Adapter). After that I am not able to telnet to localhost port 2222. I tried from scratch, removing sandbox and import it again. I still have the same problem. Now I am stuck with telnet issue and doesnt know how to troubleshoot or fix the issue. I tried all the possibilities, import the sandbox, again, check network settings, cable connected, port forwarding. no luck. can some one help me get rid of this.

Hello Bansal, Thanks for your reply.

the statement returned nothing.

I think i figured out what the issue is. no agent listening to that port. when flume listens, telnet works.

When I start the Flume agent and when the agent is running/listening to the port 2222 in localhost, my telnet works without any issues. as soon as i kill my flume agent , telnet stops working. looks like I got some understanding on how flume agent works. will continue my learning ..

Thanks,

Ram
