So, I sniffed out the conversation between my working kafka-mesos scheduler and the mesos master, and something I picked up that Wireshark pointed out was that there were 0 server packets in this conversation. So the scheduler is simply POST-ing, and while it’s talking to the socket, it doesn’t really receive any feedback, which explains why my non-working example appears fine, but is not doing anything.
It still seems fairly clear that if there were firewall rules interfering, the POST would fail, and I confirm that I can telnet to the port. What other reasons might a framework registration fail? Marathon has no trouble registering a framework and launching jobs on this cluster, only kafka-mesos. :/ From: Justin Ryan <[email protected]<mailto:[email protected]>> Reply-To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Date: Monday, April 18, 2016 at 1:50 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Re: kafka-mesos still refusing to launch brokers on one cluster Nope, nothing about the scheduler trying to connect. :/ I agree the message isn’t making it there – this is why I fired up tcpdump, and attached the HTTP conversation to my original message, because it’s not a particularly sensible HTTP conversation from my POV, but the scheduler is talking to the socket for the mesos API. I’m running the scheduler on the same host, and there are no relevant firewall rules, all tables (almost said chains ;d) are ACCEPT. I suppose I could try tcpdump on a successful register on the working cluster and see what’s diff, I’ll try this and report back.

If not, the registration message from the scheduler is not making it to the master. Are there any firewall rules between the scheduler host and master host? ________________________________ P Please consider the environment before printing this e-mail The information in this electronic mail message is the sender's confidential business and may be legally privileged.
