Subject [jira] [Resolved] (AURORA-1223) Modify scheduler updater to not use "watch_secs" for health-check enabled jobs
Date Tue, 06 Sep 2016 18:03:20 GMT

Kai Huang resolved AURORA-1223.
-------------------------------
    Resolution: Fixed

After discussion on Aurora dev list, it turns out there will be no scheduler-side change associated
with this issue.

Our final conclusion is that we adopt the following implementation:

If the users want purely health checking driven updates they can set watch_secs to 0 and enable
health checks.  (watch_secs=0 is not allowed at client side, we will relax this constraint
after we modified executor. However, no scheduler change is required since scheduler allows
non-negative values for watch_secs)

If they want to have both health checking and time driven updates they can set watch_secs
to the time that they care about, and doing health checks at STARTING state as well.

If they just want time driven updates they can disable health checking and set watch_secs
to the time that they care about..
