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
