> 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.
