------------------------------
Summary: Hybrid Shuffle may face deadlock when running a task need
to execute big size data
Key: FLINK-29923
URL: https://issues.apache.org/jira/browse/FLINK-29923
Project: Flink
Issue Type: Bug
Components: Runtime / Network
Affects Versions: 1.11.6
Reporter: AlexHu
Attachments: 性能差距.png, 死锁2-select.png, 死锁检测.png
The flink 1.11.6 offers hybrid shuffle to combine the superiority of blocking
shuffle and pipeline shuffle. But when I want to test this new feature I face a
problem that it may cause deadlock when it running.
Actually, it will run well at beginning. However, when it runs to a certain
number it may failure for the buffer size and if I set a bigger size it may
running without data execution like the picture. So I want to ask the cause of
this problem and a solution.
