Siddharth Ahuja commented on YARN-10063:
----------------------------------------

Thanks [~wilfreds], the spacing before the modifier is intentional as it brings 
in the number closer and makes it neater.

Before:

{code:java}
       where command and command-args: 
            initialize container:   0 appid tokens nm-local-dirs nm-log-dirs 
cmd app...
            launch container:       1 appid containerid workdir 
container-script tokens --http | --https keystorepath truststorepath pidfile 
nm-local-dirs nm-log-dirs resources 
 [DISABLED] launch docker container:       4 appid containerid workdir 
container-script tokens --http | --https keystorepath truststorepath pidfile 
nm-local-dirs nm-log-dirs docker-command-file resources 
...
{code}

After:

{code:java}
       where command and command-args: 
            initialize container:   0 appid tokens nm-local-dirs nm-log-dirs 
cmd app...
            launch container:       1 appid containerid workdir 
container-script tokens http-option pidfile nm-local-dirs nm-log-dirs resources 
                                      where http-option is one of:
                                      --http
                                      --https keystorepath truststorepath
 [DISABLED] launch docker container: 4 appid containerid workdir 
container-script tokens http-option pidfile nm-local-dirs nm-log-dirs 
docker-command-file resources 
...
{code}

The spaces next to the ":" are varying. That is to say, they are not consistent 
per command. Therefore, I could modify them to look neater and not break 
anything.

> YARN-8448/YARN-6586 seems to have introduced a new option - "\--http" 
> (default) and "\--https" that is possible to be passed in to the 
> container-executor binary, see :
> https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/container-executor/impl/main.c#L564
> and 
> https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/container-executor/impl/main.c#L521
> however, the usage output seems to have missed this:
> https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/container-executor/impl/main.c#L74
> Raising this jira to improve this.
