[jira] [Commented] (MESOS-1791) Introduce Master / Offer Resource Reservations aka Quota
[ https://issues.apache.org/jira/browse/MESOS-1791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=14714507#comment-14714507 ] Alexander Rukletsov commented on MESOS-1791: [~hbogert], both reserve resources per role. The differences are that dynamic reservations are tied to particular agents (slaves) and can be controlled by frameworks, while quotas are cluster-wide and managed by operators. I would encourage you to take a look at the design doc (MESOS-2936) for more information. Introduce Master / Offer Resource Reservations aka Quota Key: MESOS-1791 URL: https://issues.apache.org/jira/browse/MESOS-1791 Project: Mesos Issue Type: Epic Components: allocation, master, replicated log Reporter: Tom Arnfeld Assignee: Alexander Rukletsov Labels: mesosphere Currently Mesos supports the ability to reserve resources (for a given role) on a per-slave basis, as introduced in MESOS-505. This allows you to almost statically partition off a set of resources on a set of machines, to guarantee certain types of frameworks get some resources. This is very useful, though it is also very useful to be able to control these reservations through the master (instead of per-slave) for when I don't care which nodes I get on, as long as I get X cpu and Y RAM, or Z sets of (X,Y). I'm not sure what structure this could take, but apparently it has already been discussed. Would this be a CLI flag? Could there be a (authenticated) web interface to control these reservations? -- This message was sent by Atlassian JIRA (v6.3.4#6332)

Could one say that dynamic reservations is a more restricted form of quotas, as the latter does not lay reservation on specific resources/slaves? Or are they the same thing?

For example, both Cassandra framework and HDFS framework belongs to role1, and HDFS dynamically reserves some resources in an agent for role1, then I think it may be possible for allocator to offer those resources to Cassandra since it also belongs to role1, but actually HDFS expects to be offered with those resources.

There was also a [talk on MesosCon|http://mesoscon2015.sched.org/event/7151c36724e5c3bc9de9e452fe4c866a#.Vd5uBtOqqko], hopefully the video will be available soon. If your question will remain unanswered, I would like to encourage you to continue on the devlist rather than quota epic, so that other contributors may chime in.
