-----------------------------------------
Summary: 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
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}
