Key: FLINK-36585 URL: https://issues.apache.org/jira/browse/FLINK-36585 Project: Flink Issue Type: Bug Components: Connectors / Common Affects Versions: 2.0-preview Reporter: Jiangjie Qin
This is an issue introduced in FLINK-35924. The SplitFetcherManager.close() may chain the fetcher status check to the element queue availability future in a tight loop. This may cause problems such as OOM if the fetcher closure takes long. The fix is straightforward. We just need to blocking waiting on each check. -- This message was sent by Atlassian Jira (v8.20.10#820010)
