----------------------------
Summary: Reverse DNS for cert validation ?
Key: MESOS-4665
URL: https://issues.apache.org/jira/browse/MESOS-4665
Project: Mesos
Issue Type: Bug
Affects Versions: 0.26.0
Reporter: pawan
I have three mesos master nodes configured to use SSL and with cert validation
enabled. All the machines are failing cert-validation and hence the peering
with the following error:
I0212 14:02:22.019564 20544 network.hpp:463] ZooKeeper group PIDs: {

>From my understanding and looking at the source, during cert validation, mesos
>uses getnameinfo call to get the hostname of the connecting peer using the IP
>address on the socket connection. Everything worked when I added host-ip
>mappings of all peers to /etc/hosts on each host.
Does mesos inherently expect reverse DNS (PTR records) to be provisioned ? If
so, this is very challenging and unrealistic expectation. Even worse if you are
deploying mesos in a firewalled/NAT-ed environment.
Is my understanding right ? Am I missing anything here ? How would you
recommend me to proceed ?
Also, I use --hostname to set hostname of all mesos nodes and see the right
[ip, hostname] info in zookeeper node. Looks like mesos is not using it during
cert validation.
