Wangda Tan commented on YARN-3581:
----------------------------------
Think about this, this is not a critical issue for 2.7.1, so I think it's
better not to commit to 2.7.1. Removed it from target version. Committing.

> 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.
