--------------------------------------
if node-label-expression in ApplicationSubmissionContext is set, it is used for
all containers.

Specifying node label for application
Applications can use following Java APIs to specify node label to request
- ApplicationSubmissionContext.setNodeLabelExpression(..) to set node label
expression for all containers of the application.
- ResourceRequest.setNodeLabelExpression(..) to set node label expression for
individual resource requests. This can overwrite node label expression set in
ApplicationSubmissionContext
- Specify setAMContainerResourceRequest.setNodeLabelExpression in
ApplicationSubmissionContext to indicate expected node label for application
master container.

> I thought this app will be worked as follows according to resources.json
> - slider-appmaster should be allocated to a host whose node label is “label1”.
> - HBASE_REGIONSERVER should be allocated to a host whose node label is
> default.
> but, all containers was trying to allocate to a host whose node label is
> “label1"
