Subject [jira] [Created] (HELIX-625) Provide mechanism to react to disconnection due to flapping
Date Thu, 14 Jan 2016 23:22:39 GMT
Marco P. created HELIX-625:

             Summary: Provide mechanism to react to disconnection due to flapping
                 Key: HELIX-625
                 URL: https://issues.apache.org/jira/browse/HELIX-625
             Project: Apache Helix
          Issue Type: Improvement
          Components: helix-core
    Affects Versions: 0.7.1, 0.7.2, 0.6.x, master
            Reporter: Marco P.
            Priority: Minor

ZKHelixManager can detect an instance flapping and shut down.


Currently there is no mechanism for the application to learn about this event (and react to
it). The application will be "silently" excluded from participation, stop receiving notifications,
updates, etc.

A mechanism should exist for the application to be notified, allowing it to react in the appropriate
application-specific way (ignore, shutdown, restart, raise alert, ...).
