A while ago, I posted a few diffs where this object was called `Interval` (https://reviews.apache.org/r/36321/diff/7/). The reason why it was changed back to `Unavailability` is that we may wish to extend this object to be more specific, in the future. (We've already removed all the maintenance-specific language in the comments for `Unavailability` and `InverseOffer`.) Taking your example, the custom allocator asks for resources back. It says that these will be unavailable by the `start` time. Duration is optional; in the case of maintenance, when `duration` is omitted, it means the duration is forever or unknown. I think the term also works for non-maintenance uses. - Joseph ----------------------------------------------------------- This is an automatically generated e-mail.
