[jira] [Created] (SYSTEMML-2154) Misleading explain recompile_hop output

Matthias Boehm created SYSTEMML-2154:
----------------------------------------

             Summary: Misleading explain recompile_hop output
                 Key: SYSTEMML-2154
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-2154
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


Since the major refactoring of the existing recompiler in SYSTEMML-2072 (common code path), the explain recompile_hops flag returns misleading output. Specifically, during recompilation, the recompiler creates and updates a deep copy of the HOP DAG but the explain output shows the old (not updated) DAG.
