Yuxin Tan created FLINK-34544: --------------------------------- 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
