--------------------------------------
Assignee: (was: Marcelo Vanzin)
> SystemClock uses non-monotonic time in its wait logic
> -----------------------------------------------------
>
> Key: SPARK-10614
> URL: https://issues.apache.org/jira/browse/SPARK-10614
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.3.0
> Reporter: Steve Loughran
> Priority: Minor
>
> The consolidated (SPARK-4682) clock uses {{System.currentTimeMillis()}} for
> measuring time, which means its {{waitTillTime()}} routine is brittle against
> systems (VMs in particular) whose time can go backwards as well as forward.
> For the {{ExecutorAllocationManager}} this appears to be a regression.
