Wangda Tan created YARN-3581:
Summary: Drop -directlyAccessNodeLabelStore in RMAdminCLI
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Wangda Tan
Assignee: Wangda Tan
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.
