> Key: MESOS-3552
> URL: https://issues.apache.org/jira/browse/MESOS-3552
> Project: Mesos
> Issue Type: Bug
> Components: master
> Affects Versions: 0.24.1
> Reporter: Mandeep Chadha
> Assignee: Mandeep Chadha
>
> result.cpus() == cpus() check is failing due to ( double == double )
> comparison problem.
> Root Cause :
> Framework requested 0.1 cpu reservation for the first task. So far so good.
> Next Reserve operation — lead to double operations resulting in following
> double values :
> results.cpus() : 23.9999999999999964472863211995 cpus() : 24
> And the check ( result.cpus() == cpus() ) failed.
> The double arithmetic operations caused results.cpus() value to be :
> 23.9999999999999964472863211995 and hence ( 23.9999999999999964472863211995
> == 24 ) failed.
