ParameterSpace

Defines a parameter space to be used by the scheduler to create a joblet set. A parameter space may consist of rows of columns or a list of columns that is expanded and can be turned into a cross product. Use appendRow to create a rowMajor parameter space or appendCol to define a column expansion. You cannot use both appendRow() and appendCol() in the same ParameterSpace. Once the scheduler defines a slice of the parameter space for a given Joblet, the scheduler creates JobletParameterSpace instances for each Joblet. This slice of the parameter space is delivered to the resource. To limit how many Joblets or the number of rows in a Joblet, use setMaxJobletSize or use the jobletCount argument to schedule() or SchedulSpec.
