----------------------------------------------------------------
Flink does not give guarantees for the number of threads per task slot. Each
unchained operator runs as a thread and some operators such as sorts are
executed in multiple threads.
So depending on the JobGraph there can be 10 or more threads per task slot.
Do you know what the termination condition of a {{LinuxContainerExecutor}} is?

> Project: Flink
> Issue Type: Improvement
> Components: YARN Client
> Affects Versions: 0.10
> Reporter: Ufuk Celebi
>
> Currently, the number of vcores per YARN container is set to 1.
> It is desirable to allow configuring this value. As a simple heuristic it
> makes sense to at least set it to the number of slots per container.
