-----------------------------------

Hi [~leftnoteasy],[~kkaranasos]

Sorry for the late response, I was on vacation.
{quote}for the md.vm format, any advantages in this format
{quote}
this format of markdown file can help to substitute ${project.version} variable 
to the under-building version. I think we need to rename it back otherwise the 
doc will be looking like following

{code}
$ yarn org.apache.hadoop.yarn.applications.distributedshell.Client -jar 
share/hadoop/yarn/hadoop-yarn-applications-distributedshell-${project.version}.jar
 -shell_command sleep -shell_args 10 -placement_spec PlacementSpec
{code}

what do you think?

> Currently it is very confusing to have the two configs in two different files 
> (yarn-site.xml and capacity-scheduler.xml). 
>  
> Maybe a better approach is: we can delete the scheduling-request.allowed in 
> CS, and update placement-constraints configs in yarn-site.xml a bit: 
>  
> - Remove placement-constraints.enabled, and add a new 
> placement-constraints.handler, by default is none, and other acceptable 
> values are a. external-processor (since algorithm is too generic to me), b. 
> scheduler. 
> - And add a new PlacementProcessor just to pass SchedulingRequest to 
> scheduler without any modifications.
