Hi all, I wanted to take a moment to thank Alexandra Sava, who completed her OPW internship this past week. We worked together in the second half of her internship to create a design document for maintenance primitives in Mesos (the original ticket is MESOS-1474 <https://issues.apache.org/jira/browse/MESOS-1474>, but the design document is the most up-to-date plan).
Maintenance in this context consists of anything that requires the tasks running on the slave to be killed (e.g. kernel upgrades, machine decommissioning, non-recoverable mesos upgrades / configuration changes, etc). The desire is to expose maintenance events to frameworks in a generic manner, as to allow frameworks to respect their SLAs, perform better task placement, and migrate tasks if necessary. The design document is here: https://docs.google.com/document/d/1NjK7MQeJzTRdfZTQ9q1Q5p4dY985bZ7cFqDpX4_fgjM/edit?usp=sharing Please take a moment before the end of next week to go over this design. *Higher level feedback and questions can be discussed most effectively in this thread.* Let's thank Alexandra for her work! Ben
