create

public SpaceViolationPolicyEnforcement create(RegionServerServices rss,
                                              TableName tableName,
                                              SpaceQuotaSnapshot snapshot)

Constructs the appropriate SpaceViolationPolicyEnforcement for tables that are in violation of their space quota.

createWithoutViolation

public SpaceViolationPolicyEnforcement createWithoutViolation(RegionServerServices rss,
                                                              TableName tableName,

Creates the "default" SpaceViolationPolicyEnforcement for a table that isn't in violation. This is used to have uniform policy checking for tables in and not quotas. This policy will still verify that new bulk loads do not exceed the configured quota limit.

Parameters:

rss - RegionServerServices instance the policy enforcement should use.

tableName - The target HBase table.

snapshot - The current quota snapshot for the tableName, can be null.
