Adam B commented on MESOS-4189:
-------------------------------
I spoke to [~jvanremoortere] about committing dynamic weights in time for Mesos
0.28, and his biggest concern was the lack of tests for the registry changes
(MESOS-4797), since the registry is a critical and complex piece of Mesos.
Additional TODOs from my conversation with Joris:
- MESOS-4316: He'd prefer to see a GET for /weights in the same release as the
PUT/POST. We can't change what's displayed in /roles without going through a
deprecation cycle, but we can show the weights in both places for now.
- (no JIRA yet): Rescind all outstanding offers, to facilitate satisfying the
updated weights. Since the current behavior requires restarting the master, all
outstanding offers would be rescinded anyway. This can be done in a new patch.
See how quota handles rescinding offers after updating the allocator:
https://github.com/apache/mesos/blob/0.28.0-rc1/src/master/quota_handler.cpp#L319
- MESOS-3945: Update docs to reference the change for 0.29 instead of 0.28. The
0.28.0-rc1 has already been cut, so any non-critical fixes/features have to
wait until 0.29, which should only be a month away.
That said, I'll review the current patches soon so we can get them committed
for 0.29 and work on landing the registry tests and rescind behavior asap.
