[Benjamin Mahler]

Hi folks, just a reminder that there is indeed a performance working group
meeting tomorrow.

We'll discuss what's been going on recently in the performance area, and
there's a lot to discuss! I will send out some detailed notes to the
mailing lists afterwards.

Re: 1.7 release manager?

[Gastón Kleiman]

I haven't been waiting for this, but I'd like to volunteer too. I've never
been the release manager before, so I could help with some of the
pre-release JIRA wrangling and drafting the announcements.

Unfortunately the time conflicts with the CSI community sync so I'll have
to skip :(

Re: Backport Policy

[Chun-Hung Hsiao]

I just have a comment on a special case:
If a fix for a flaky test is easy to backport,
IMO we probably should backport it,
otherwise if someone backports another critical fix in the future,
it would take them extra effort to check all CI failures.

Flink on Mesos - have to manually add host name to /etc/hosts

[NEKRASSOV, ALEXEI]

When I attempted to start Flink 1.4.2 on Mesosphere DC/OS Version 1.11.1 - I've 
ran into the issue described here: 
https://stackoverflow.com/questions/45391980/error-installing-flink-in-dcos
This workaround solved the problem: https://stackoverflow.com/a/48184752

Is there something that can be changed in the Mesos project, to avoid this 
issue? Or is there a place to document it along with the workaround?



We are trying to find the IP of localhost from container, right? Why not use 
'127.0.0.1' instead of `hostname -f` followed by name resolution?..

https://github.com/mesosphere/dcos-flink-service/blob/1.4.2/container/appmaster/runit/service/flink/run#L37


Please note that hostname resolves fine on the VM (through DNS resolution). It 
is only in the container where it fails (unless we edit /etc/hosts).

Thanks,
Alex Nekrassov

[VOTE] Move the project repos to gitbox

[Vinod Kone]

Hi,

As discussed in another thread and in the committers sync, there seem to be
heavy interest in moving our project repos ("mesos", "mesos-site") from the
"git-wip" git server to the new "gitbox" server to better avail GitHub
integrations.

Please vote +1, 0, -1 regarding the move to gitbox. The vote will close in
3 business days.

Thanks,
Vinod
