Subject [jira] [Resolved] (AURORA-1148) Display All Scheduling Veto Reasons for PENDING tasks
Date Fri, 17 Apr 2015 21:57:58 GMT


Bill Farner resolved AURORA-1148.
    Resolution: Fixed

I believe AURORA-911 is the closest we should come to addressing what's requested in this
ticket.  As Maxim notes, an exhaustive veto list would be daunting and likely counterproductive.

> Recently I was triaging an instance that would not schedule, and although I was validating
many possibilities, I did get sidetracked when I saw that 'Insufficient RAM' was listed as
the reason.
> In fact, there was also insufficient Disk, CPU, and hosts, as this was a task which had
a dedicated constraint.
> In order to give more information, we should ensure we're exposing all Vetoes to help
narrow if there is just one resource preventing scheduling, or many (all resources may point
to a lack of hosts overall, for instance).
> I did notice both AURORA-377 and AURORA-911, but both seem unrelated to this.
