GitHub user sheepduke opened a pull request:
https://github.com/apache/spark/pull/15579
Added support for extra command in front of spark.
## What changes were proposed in this pull request?
A minor functional change is added into yarn facility to make it possible
for users to add some command prefix before spark. Such as "numactl
--cpunodebind=1 ...". This makes it useful in some cases to do some
optimization work.
## How was this patch tested?
Since it is only a minor functional patch, it is re-compiled and tested on
our cluster with BigBench to make sure that it works properly.
