----------------------------------------------------------------
[~seonggon], let's temporarily disable `hive.optimize.shared.work` in the q
test to unblock the development and create a separate ticket to address the OOM
issue.
Note, it should be labeled as `hive-4.1.0-must`. If we don't find a proper
solution, we should rollback .

> Issue Type: Sub-task
> Affects Versions: 4.0.0-alpha-2
> Reporter: Seonggon Namgung
> Assignee: Seonggon Namgung
> Priority: Major
> Labels: hive-4.1.0-must, pull-request-available

> A DAG created by OperatorGraph is not equal to the corresponding DAG that is
> submitted to Tez.
> Because of this problem, ParallelEdgeFixer reports a pair of normal edges to
> a parallel edge.
> We observe this problem by comparing OperatorGraph and Tez DAG when running
> TPC-DS query 71 on 1TB ORC format managed table.
