Method Detail

getProto

public YarnProtos.ResourceProto getProto()

getMemory

public int getMemory()

Description copied from class: Resource

Get memory of the resource.

Specified by:

getMemory in class Resource

Returns:

memory of the resource

setMemory

public void setMemory(int memory)

Description copied from class: Resource

Set memory of the resource.

Specified by:

setMemory in class Resource

Parameters:

memory - memory of the resource

getVirtualCores

public int getVirtualCores()

Description copied from class: Resource

Get number of virtual cpu cores of the resource. We refer to virtual cores to clarify that these represent normalized cores which may have a m:n relationship w.r.t physical cores available on the compute nodes. Furthermore, they also represent idealized cores since the cluster might be composed of heterogenous nodes.

Specified by:

getVirtualCores in class Resource

Returns:

num of virtual cpu cores of the resource

setVirtualCores

public void setVirtualCores(int vCores)

Description copied from class: Resource

Set number of virtual cpu cores of the resource. We refer to virtual cores to clarify that these represent normalized cores which may have a m:n relationship w.r.t physical cores available on the compute nodes. Furthermore, they also represent idealized cores since the cluster might be composed of heterogenous nodes.

Specified by:

setVirtualCores in class Resource

Parameters:

vCores - number of virtual cpu cores of the resource

compareTo

public int compareTo(Resource other)
