Review request for mesos, Andrei Sekretenko and Meng Zhu. Bugs: MESOS-9871 https://issues.apache.org/jira/browse/MESOS-9871 Repository: mesos Description ------- Quota consumption is computed as follows: Allocation + Unallocated Reservation == Reservations + Unreserved Allocation That is, reservations count towards quota regardless of whether they're allocated. Allocation counts towards quota. Offered resources *do not* count towards quota, this is to (1) provide stability of the quota consumption metrics in the face of offers flowing in and out, and (2) to ensure that we treat offers as rescindable and therefore not yet "counting" towards quota. Also, if in the future schedulers are offered more than their quota to improve their choices, counting offered resources as quota consumption will be problematic. Diffs ----- src/master/framework.cpp c35de2574ef683a9f397a957422fdbf8fa751313 src/master/master.hpp 23dafe746b6f9b3d70ad7220f54c4d49068b8af8 Diff: https://reviews.apache.org/r/71029/diff/1/ Testing ------- Added a test in a subsequent patch.
