Subject Re: [DISCUSS] Secure Flink clusters
Date Tue, 17 May 2016 15:35:34 GMT
Hi Eron,

thanks a lot for putting so much effort into the design document. You've
probably spend a lot of time to come up with it!
I have to admit that I'm not that familiar with the topic, so I probably
need to re-read it again to digest it completely.

What are your plans for implementing the proposed changes? (time-wise and
people-wise?) I'm asking to get an idea of when we can expect the changes
in the master, in releases, ...

I think Stefano Baghino also had some discussions about improving Flink's
security on the mailing list recently. Maybe you guys can sync your efforts
and collaborate on this.
