--------------------------------
Uploaded patch v4.
# Fixed divide-by-zero in {{stjp.getNumNodes()/stjp.getNodesPerRack()}}. My
bad, the correct jira is YARN-6551.
# The intention is to make sure count cannot be less than 1. So I use
{{Math.max}}.
# Added doc for that.
> Make SLS JSON input file format simple and scalable

> SLS input format is verbose, and it doesn't scale out. We can improve it in
> these ways:
> # We need to configure tasks one by one if there are more than one task in a
> job, which means the job configuration usually includes lots of redundant
> items. To specify the number of task for task configuration will solve this
> issue.
> # Container host is useful for locality testing. It is obnoxious to specify
> container host for each task for tests unrelated to locality. We would like
> to make it optional.
> # For most tests, we don't care about job.id. Make it optional and generated
> automatically by default.
> # job.finish.ms doesn't make sense, just remove it.
> # container type and container priority should be optional as well.
