Subject Spark on kubernetes : missing spark.kubernetes.driver.request.cores parameter ?
Date Fri, 04 Oct 2019 15:52:35 GMT
Hello all,

I am surprised that it is not possible to define
"spark.kubernetes.driver.request.cores" when submitting a spark job on
kubernetes.

My understanding is that it would limit the CPU requests for the driver on
the k8s cluster and we could still define how many cores (threads) we use in
the driver with spark.driver.cores.

In the 2.4 branch, the request is then defined by "spark.driver.cores", so
we cannot throttle the driver.

Is my understanding wrong or I missed something ?

Thanks
Christophe
