> In the attached script, the resulting PersisentWrites for {{doutc1_agg}} & {{dWc1_agg}}
end up having unknown block sizes, despite the input DAGs for those variables having known
block sizes.  Due to this, when we use MLContext and mark those variables as outputs, the
PersistentWrites will be rewritten to TransientWrites, and the block sizes will remain unknown.
> To run:
> {code}
> spark-submit $SYSTEMML_HOME/target/SystemML.jar -f scenario1.dml -explain recompile_hops
> {code}
