Specified by:

getNodeId in class Container

Returns:

identifier of the node on which the container is allocated

setId

public void setId(ContainerId id)

Specified by:

setId in class Container

getNodeHttpAddress

public String getNodeHttpAddress()

Description copied from class: Container

Get the http uri of the node on which the container is allocated.

Specified by:

getNodeHttpAddress in class Container

Returns:

http uri of the node on which the container is allocated

setNodeHttpAddress

public void setNodeHttpAddress(String nodeHttpAddress)

Specified by:

setNodeHttpAddress in class Container

getResource

public Resource getResource()

getContainerToken

public Token getContainerToken()

Description copied from class: Container

Get the ContainerToken for the container.

ContainerToken is the security token used by the framework to verify authenticity of any Container.

The ResourceManager, on container allocation provides a secure token which is verified by the NodeManager on container launch.

Applications do not need to care about ContainerToken, they are transparently handled by the framework - the allocated Container includes the ContainerToken.

Specified by:

getContainerToken in class Container

Returns:

ContainerToken for the container
