Subject [GitHub] flink issue #2276: [FLINK-4201] [runtime] Forward suspend to checkpoint coor...

Github user uce commented on the issue:

    Thanks for taking a look, Stephan.
    Regarding your question: *Would we interfere with such a setup when removing checkpoints
on "suspend" in "standalone" mode?*:
    Yes, we would interfere, but what you describe is currently **not** possible with Flink
(that is no one can run it like that). The problem is that recovery on the master is tightly
coupled to ZooKeeper (configured via `recovery.mode: ZOOKEEPER`). I really like your idea
and agree that it should be possible to run an HA setup like that. I will open an issue for
it. Do you think it's important to fix this for 1.1 already?
    Regarding the name *standalone*:
    I fully agree. We have a standalone cluster mode and standalone recovery mode. Our standalone
recovery mode (`recovery.mode: STANDALONE`) actually means `NO_RECOVERY`. I think that's what
also made you assume that what you describe is possible, right? 

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
