Nodemap constraint is a property check in the stage. The
paralell execution of the job can be restriced to a
particular node or nodes at a stage level with this check.
It provides a drop down list of nodes available and by
selecting a particular node or nodes the job executes only
on that particular node or nodes.
For example, if the incoming data is being processed in
parallel mode on 4 nodes then in the next stage if the
nodemap constraint is checked and only 1 node is selected
then the entire data is processed in a sequential mode i.e.
on that particular node.
In case the incoming data processes on 4 nodes and nodemap
contraint is checked and 2 nodes are selected then the data
is distributed on these 2 nodes and the job process is
carried out on the same.
