reswqa opened a new pull request, #20487:
URL: https://github.com/apache/flink/pull/20487
## What is the purpose of the change
*Based on TPC-DS test, we found that hybrid shuffle can't schedule the graph
contains blocking edge. The reason is that some batch operators will forcibly
set the exchange mode to blocking, which breaks ALL_ EDGE_HYBRID‘s constraint
and may cause scheduling deadlock. We should use a better way to support the
scheduling of all kinds of edges, including hybrid edge.*

to Junit5 and AssertJ.*
- *`PipelinedRegionSchedulingStrategy` supports all `ResultPartitionType`.*
