cluster-computing mesos mesosphere bigdata

Do we need to have configuration files in all mesos masters?

I am running a mesos cluster with 3 mesos masters. I have enable authentication and saved a credentials.json file in one of the master. I would like to know if we have to put this file in all 3 mesos masters? Same applies to other files like acls.json and other parameter files.

Solution

Yes you have to copy your config files to all masters in the cluster.

Mesos masters do not exchange this configuration information, nor it is persisted across failover. If a currently leading master fails over to another one, you probably want the new leader have the same configuration around authentication and authorization.
