问题
I am building a mesos cluster from scratch (using Vagrant, which is not relevant for this issue). OS: Ubuntu 16.04 (trusty) Setup:
- Master -> Runs ZooKeeper, Mesos-master, Marathon and Chronos
- Slave -> Runs Mesos-slave
This is my provisioning script for the master node https://github.com/zeitgeist2018/infrastructure/blob/fix-marathon/provision/scripts/install-master.sh.
I have managed to register de slave into Mesos, install Marathon and Chronos frameworks, and run scheduled jobs in Chronos (both with docker and shell commands), but I can't get Marathon to work properly. The UI gets stuck in "Loading applications" as soon as I open it, and when I try to call the API, the request hangs forever with no response. In the API I tried to get simple marathon information and do deployments, both with the same hanging result. I've been checking Marathon logs but I don't see anything error there. Just a couple of logs that may (or not) be a hint:
[2020-03-08 10:33:21,819] INFO Prompting Mesos for a heartbeat via explicit task reconciliation (mesosphere.marathon.core.heartbeat.MesosHeartbeatMonitor$$anon$1:marathon-akka.actor.default-dispatcher-6)

I have managed to make it work. It was as simple as downgrading Marathon to v1.7.189. After that, it starts properly, and the API responds to requests.
