Method Detail

testElementUniquenessAndFIFO

public void testElementUniquenessAndFIFO()
                                  throws Exception

Throws:

Exception

testPriorityAndFIFO

public void testPriorityAndFIFO()
                         throws Exception

Throws:

Exception

testConcurrentPut

public void testConcurrentPut()
                       throws Exception

Test that the uniqueness constraint is honored in the face of concurrent modification.

Throws:

Exception

testTake

public void testTake()
              throws Exception

Test that calls to RegionNormalizerWorkQueue.take() block the requesting thread. The producing thread places new entries onto the queue following a known schedule. The consuming thread collects a time measurement between calls to take. Finally, the test makes coarse-grained assertions of the consumer's observations based on the producer's schedule.

Throws:

Exception

drainTo

private static <E> void drainTo(org.apache.hadoop.hbase.master.normalizer.RegionNormalizerWorkQueue<E> queue,
                                Collection<E> dest)
                         throws InterruptedException

Throws:

InterruptedException
