---------------------------------
Summary: The release check bug in tiered memory manager of hybrid
shuffle
Key: FLINK-34544
URL: https://issues.apache.org/jira/browse/FLINK-34544
Project: Flink
Issue Type: Bug
Components: Runtime / Network
Affects Versions: 1.19.0
Reporter: Yuxin Tan
Assignee: Yuxin Tan
The `TieredStorageMemoryManagerImpl` has a `numRequestedBuffers` check when
releasing resources. However, this check is performed in the task thread, while
the buffer recycle may occur in the Netty thread. As a result, it may
incorrectly throw an exception when the release is too quick for the vertex,
which has almost no data.
We should fix it.
