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

hi [~wangda],

Regarding deprecated message as argument, {{-removeFromClusterNodeLabels}} had 
a comment that {{(label splitted by ",")}}, so thought imp info can be shown in 
this way. will move it to description . but one more thing, shall i totally 
remove description and have only this Deprecated message, so that no one will 
use it ?
others will get it corrected.

> Deprecate -directlyAccessNodeLabelStore in RMAdminCLI

> In 2.6.0, we added an option called "-directlyAccessNodeLabelStore" to make 
> RM can start with label-configured queue settings. After YARN-2918, we don't 
> need this option any more, admin can configure queue setting, start RM and 
> configure node label via RMAdminCLI without any error.
> In addition, this option is very restrictive, first it needs to run on the 
> same node where RM is running if admin configured to store labels in local 
> disk.
> Second, when admin run the option when RM is running, multiple process write 
> to a same file can happen, this could make node label store becomes invalid.
