Hi Klaus, thanks for your reply. I am aware of the frameworks provided by mesosphere and I already tried them out in a POC setup. From looking at the HDFS documentation [1] however, the framework seems to be still in beta.
"HDFS is available at the beta level and not recommended for Mesosphere DCOS production systems." I think what my questions are boiling down to is the following: should I use a Mesos framework to manage persistency within my Mesos cluster or should I do it outside with other means - e.g. using Ambari to setup a shared HDFS etc. If I would use those frameworks, how is your experience regarding the life cycle management? Scaling out instances, upgrading to newer versions etc. Regards, Andreas [1] https://docs.mesosphere.com/manage-service/hdfs/ On Tue, Feb 9, 2016 at 1:05 AM, Klaus Ma <[email protected]> wrote: > Hi Andreas, > > I think Mesosphere has done some work on your questions, would you check > related repos at https://github.com/mesosphere ? > > > On Mon, Feb 8, 2016 at 9:43 PM Andreas Fritzler < > [email protected]> wrote: > >> Hi, >> >> I have a couple of questions around the persistency topic within a Mesos >> cluster: >> >> 1.
