Dynamically sizing a mesos cluster.
Hi,
Is there any functionality in Mesos to dynamically resize a cluster? I want
to be able to add and remove slave nodes and maybe masters while the
cluster is running.
Thanks,
Doug

We'll likely be working on some added support for "host drain" in the not
too distant future too, see
MESOS-544<https://issues.apache.org/jira/browse/MESOS-544>
.

Not sure if this is what you are asking, but:
-- To kill/remove a master or slave: just issue a SIGTERM to the
mesos/slave process.
-- To add a master/slave just start them as you typically do.
Note that removing a slave causes all the tasks on it to go LOST. It is the
responsibility of the framework to reschedule them on to active slaves.
HTH,

Great! How? I have not found the information yet in reading the docs. If I
am missing it, please let me know where to look.

Absolutely. The adding and removing themselves must be done out of band though.
