Michael Park updated MESOS-2018:
--------------------------------
Description:
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 reserve offered
resources, such that 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.
