Example 1 with ContainersResponse

use of org.apache.hadoop.ozone.recon.api.types.ContainersResponse in project ozone by apache.

the class TestContainerEndpoint method testGetContainers.

@Test
public void testGetContainers() {
    Response response = containerEndpoint.getContainers(-1, 0L);
    ContainersResponse responseObject = (ContainersResponse) response.getEntity();
    ContainersResponse.ContainersResponseData data = responseObject.getContainersResponseData();
    assertEquals(2, data.getTotalCount());
    List<ContainerMetadata> containers = new ArrayList<>(data.getContainers());
    Iterator<ContainerMetadata> iterator = containers.iterator();
    ContainerMetadata containerMetadata = iterator.next();
    assertEquals(1L, containerMetadata.getContainerID());
    // Number of keys for CID:1 should be 3 because of two different versions
    // of key_two stored in CID:1
    assertEquals(3L, containerMetadata.getNumberOfKeys());
    containerMetadata = iterator.next();
    assertEquals(2L, containerMetadata.getContainerID());
    assertEquals(2L, containerMetadata.getNumberOfKeys());
    // test if limit works as expected
    response = containerEndpoint.getContainers(1, 0L);
    responseObject = (ContainersResponse) response.getEntity();
    data = responseObject.getContainersResponseData();
    containers = new ArrayList<>(data.getContainers());
    assertEquals(1, containers.size());
    assertEquals(2, data.getTotalCount());
}
