SpaceViolationPolicyEnforcement

@Private
public class DisableTableViolationPolicyEnforcement
extends DefaultViolationPolicyEnforcement

A SpaceViolationPolicyEnforcement which disables the table. The enforcement counterpart to SpaceViolationPolicy.DISABLE. This violation policy is different from others as it doesn't take action (i.e. enable/disable table) local to the RegionServer, like the other ViolationPolicies do. In case of violation, the appropriate action is initiated by the master.
