>
> Attributes added to operator within a Module is not preserved.
> for example
> {code}
> class M implements Module {
> public void populateDAG(DAG dag, Configuration conf) {
> DummyOperator o1 = dag.addOperator("O1", new DummyOperator());
> o1.setOperatorProp(level1ModuleProp);
> dag.getMeta(o1).getAttributes().put(Context.OperatorContext.MEMORY_MB,
> 512);
> }
> {code}
> The above code when module is expanded attribute set on operator o1 is lost.
