Adam B reassigned MESOS-2018:
-----------------------------
Assignee: Adam B (was: Michael Park)
> Dynamic Resource Reservations
> -----------------------------
>
> Key: MESOS-2018
> URL: https://issues.apache.org/jira/browse/MESOS-2018
> Project: Mesos
> Issue Type: Improvement
> Components: allocation, framework, master, slave
> Reporter: Adam B
> Assignee: Adam B
> Labels: offer, persistence, reservations, resource, stateful,
> storage
>
> This is a feature to provide better support for running stateful services on
> Mesos such as HDFS (Distributed Filesystem), Cassandra (Distributed
> Database), or MySQL (Local Database).
> Current resource reservations (henceforth called "static" reservations) are
> statically determined by the slave operator at slave start time, and
> individual frameworks have no authority to reserve resources themselves.
> Dynamic reservations allow a framework to dynamically/lazily reserve offered
> resources at task launch time, such that when that task completes, those
> resources will only be re-offered to the same framework (or other frameworks
> with the same role).
> This is especially useful if the framework's task stored some state on the
> slave, and needs a guaranteed set of resources reserved so that it can
> re-launch a task on the same slave to recover that state.
