Examples of org.apache.hadoop.yarn.api.ContainerManager.stopContainer()

org.apache.hadoop.yarn.api.ContainerManager.stopContainer()

The ApplicationMaster requests a NodeManager to stop a {@link Container} allocated to it using this interface.

The ApplicationMaster sends a {@link StopContainerRequest} which includes the {@link ContainerId} of thecontainer to be stopped.

Currently the NodeManager sends an immediate, empty response via {@link StopContainerResponse} to signify acceptance of therequest and throws an exception in case of errors. The ApplicationMaster can use {@link #getContainerStatus(GetContainerStatusRequest)} to get updated status of the container.

@param request request to stop a container @return empty response to indicate acceptance of the request or an exception @throws YarnRemoteException

    //test remote exception
    boolean exception = false;
    try {
      StopContainerRequest stopRequest = recordFactory.newRecordInstance(StopContainerRequest.class);
      stopRequest.setContainerId(containerLaunchContext.getContainerId());
      proxy.stopContainer(stopRequest);
    } catch (YarnRemoteException e) {
      exception = true;
      System.err.println(e.getMessage());
      System.err.println(e.getCause().getMessage());
      Assert.assertTrue(EXCEPTION_MSG.equals(e.getMessage()));

        LOG.info("Going to make a legal stopContainer() request");
        StopContainerRequest request = recordFactory
            .newRecordInstance(StopContainerRequest.class);
        request.setContainerId(containerID);
        client.stopContainer(request);
        return null;

    });


    KillApplicationRequest request = Records


        // Try stopping a container - should not get an expiry error.
        StopContainerRequest stopRequest = Records.newRecord(StopContainerRequest.class);
        stopRequest.setContainerId(newTokenId.getContainerID());
        try {
          client.stopContainer(stopRequest);
        } catch (Throwable t) {
          fail("Stop Container call should have succeeded");
