HBase Column-family	For the selected table, specify the column families to which the policy applies.
HBase Column	For the selected table and column families, specify the columns to which the policy applies.

Add Validity Period	Specify a start and end time for the policy.

Table 2. Allow Conditions
Label	Description
Select Role	Specify the roles to which this policy applies. To designate a role as an Administrator, select the Delegate Admin check box. Administrators can edit or delete the policy, and can also create child policies based on the original policy.
Select Group	Specify the groups to which this policy applies. To designate a group as an Administrator, select the Delegate Admin check box. Administrators can edit or delete the policy, and can also create child policies based on the original policy. The public group contains all users, so granting access to the public group grants access to all users.
Select User	Specify the users to which this policy applies. To designate a user as an Administrator, select the Delegate Admin check box. Administrators can edit or delete the policy, and can also create child policies based on the original policy.
Permissions	Add or edit permissions: Read, Write, Create, Admin, Select/Deselect All.
Delegate Admin	You can use Delegate Admin to assign administrator privileges to the roles, groups, or users specified in the policy. Administrators can edit or delete the policy, and can also create child policies based on the original policy.

You can use the Plus (+) symbol to add additional conditions. Conditions are evaluated in the order listed in the policy. The condition at the top of the list is applied first, then the second, then the third, and so on.
You can use Deny All Other Accesses to deny access to all other users, groups, and roles other than those specified in the allow conditions for the policy.
Click Add.
