[jira] [Created] (FLINK-28799) Hybrid shuffle can't schedule graph contains blocking edge

Weijie Guo created FLINK-28799:
----------------------------------

             Summary: Hybrid shuffle can't schedule graph contains blocking edge
                 Key: FLINK-28799
                 URL: https://issues.apache.org/jira/browse/FLINK-28799
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
            Reporter: Weijie Guo


Based on TPC-DS test, we found that hybrid shuffle can't schedule 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 makes the scheduling deadlock.

We should think of a better way to support the scheduling the graph of all kinds of edges, including hybrid edge.
