Examples with PartialListInstancesException com.google.cloud.bigtable.admin.v2.models.PartialListInstancesException used on opensource projects

Example 1 with PartialListInstancesException

use of com.google.cloud.bigtable.admin.v2.models.PartialListInstancesException in project java-bigtable by googleapis.

the class BigtableInstanceAdminClientTest method testListInstancesFailedZone.

@Test
public void testListInstancesFailedZone() {
    // Setup
    Mockito.when(mockStub.listInstancesCallable()).thenReturn(mockListInstancesCallable);
    com.google.bigtable.admin.v2.ListInstancesRequest expectedRequest = com.google.bigtable.admin.v2.ListInstancesRequest.newBuilder().setParent(PROJECT_NAME).build();
    com.google.bigtable.admin.v2.ListInstancesResponse expectedResponse = com.google.bigtable.admin.v2.ListInstancesResponse.newBuilder().addInstances(com.google.bigtable.admin.v2.Instance.newBuilder().setName(INSTANCE_NAME + "1").build()).addFailedLocations(NameUtil.formatLocationName(PROJECT_ID, "us-east1-d")).build();
    Mockito.when(mockListInstancesCallable.futureCall(expectedRequest)).thenReturn(ApiFutures.immediateFuture(expectedResponse));
    // Execute
    Exception actualError = null;
    try {
        adminClient.listInstances();
    } catch (Exception e) {
        actualError = e;
    }
    // Verify
    assertThat(actualError).isInstanceOf(PartialListInstancesException.class);
    assert actualError != null;
    PartialListInstancesException partialListError = (PartialListInstancesException) actualError;
    assertThat(partialListError.getInstances()).containsExactly(Instance.fromProto(expectedResponse.getInstances(0)));
    assertThat(partialListError.getUnavailableZones()).containsExactly("us-east1-d");
}

Example 2 with PartialListInstancesException

use of com.google.cloud.bigtable.admin.v2.models.PartialListInstancesException in project java-bigtable by googleapis.

the class BigtableInstanceAdminClient method listInstancesAsync.

/**
 * Asynchronously lists all of the instances in the current project.
 *
 * <p>This method will throw a {@link PartialListInstancesException} when any zone is unavailable.
 * If a partial list is OK, the exception can be caught and inspected.
 *
 * <p>Sample code:
 *
 * <pre>{@code
 * ApiFuture<Instance> instancesFuture = client.listInstancesAsync();
 *
 * ApiFutures.addCallback(instancesFuture, new ApiFutureCallback<List<Instance>>() {
 *   public void onFailure(Throwable t) {
 *     if (t instanceof PartialListInstancesException) {
 *       PartialListInstancesException partialError = (PartialListInstancesException)t;
 *       System.out.println("The following zones are unavailable: " + partialError.getUnavailableZones());
 *       System.out.println("But the following instances are reachable: " + partialError.getInstances());
 *     } else {
 *       t.printStackTrace();
 *     }
 *   }
 *
 *   public void onSuccess(List<Instance> result) {
 *     System.out.println("Found a complete set of instances: " + result);
 *   }
 * }, MoreExecutors.directExecutor());
 * }</pre>
