-------------------------------------
> Missing Block Sizes For PersistentWrites & TransientWrites
> ----------------------------------------------------------
>
> Key: SYSTEMML-1595
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1595
> Project: SystemML
> Issue Type: Bug
> Reporter: Mike Dusenberry
> Assignee: Matthias Boehm
> Fix For: SystemML 1.0
>
> Attachments: scenario1.dml
>
>
> 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}
