   The List of Policies page appears.
   
   
2. Click Add New Policy.
   The Create Policy page appears.
   
   
3. Complete the Create Policy page as follows:

   Table 1. Policy Details

   Field	Description
   Policy Name	Enter an appropriate policy name. This name cannot be duplicated across the system. This field is mandatory.
   Queue	The fundamental unit of scheduling in yarn.
   Recursive	You can indicate whether all files or folders within the existing folder comes under the policy. Can be used instead of wildcard characters.
   Description	(Optional) Describe the purpose of the policy.
   Audit Logging	Specify whether this policy is audited. (De-select to disable auditing).
   Policy Label	Specify a label for this policy. You can search reports and filter policies based on these labels.

   Table 2. Allow Conditions

   Label	Description
   Select Group	Specify the group to which this policy applies. To designate the group as an Administrator for the chosen resource, specify Admin permissions. (Administrators can create child policies based on existing policies). The public group contains all users, so granting access to the public group grants access to all users.
   Select User	Specify a particular user to which this policy applies (outside of an already-specified group) OR designate a particular user as Admin for this policy. (Administrators can create child policies based on existing policies).
   Permissions	Add or edit permissions: Read, Write, Create, Admin, Select/Deselect All.
   Delegate Admin	When a policy is assigned to a user or a group of users those users become the delegated admin. The delegated admin can update, delete the policies. It can also create child policies based on the original policy (base policy).
