Subject Re: multiple users per flink deployment
Date Wed, 02 Aug 2017 15:29:30 GMT
Thanks for the overview.
Currently a single flink cluster seems to run all tasks with the same user.
I would want to be able to run each flink job as a separate user instead.

The update for separate read/write users is nice though.
