Package org.apache.hadoop.hbase.quotas

Class SpaceQuotaHelperForTests.SpaceQuotaSnapshotPredicate

java.lang.Object
org.apache.hadoop.hbase.quotas.SpaceQuotaHelperForTests.SpaceQuotaSnapshotPredicate
All Implemented Interfaces:
Waiter.Predicate<Exception>
Enclosing class:
SpaceQuotaHelperForTests
abstract static class SpaceQuotaHelperForTests.SpaceQuotaSnapshotPredicate extends Object implements Waiter.Predicate<Exception>
Abstraction to simplify the case where a test needs to verify a certain state on a SpaceQuotaSnapshot. This class fails-fast when there is no such snapshot obtained from the Master. As such, it is not useful to verify the lack of a snapshot.
