Junrui Lee commented on FLINK-37825: ------------------------------------ I think the issue is that your dev code does not adhere to standard YAML syntax: duplicate keys are not allowed. Standard YAML does not allow duplicate keys in a map. It states that "The content of a mapping node is an unordered set of key/value node pairs, with the restriction that each of the keys is unique." For more details, please refer to: [https://yaml.org/spec/1.2.2/#nodes] or Flink doc: [https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/config/#migrate-from-flink-confyaml-to-configyaml] > Standard YAML convert and dump failed > ------------------------------------- > > Key: FLINK-37825 > URL: https://issues.apache.org/jira/browse/FLINK-37825 > Project: Flink > Issue Type: Improvement > Components: Deployment / YARN > Affects Versions: 1.20.1 > Reporter: melin > Priority: Major > Attachments: image-2025-05-21-21-20-35-658.png > > > By adding hadoop parameters through the code, the startup has two keys > containing shortcircuit, resulting in the failure of submitting the yarn > cluster. > !image-2025-05-21-21-20-35-658.png! > !image-2025-05-19-17-20-14-702.png! -- This message was sent by Atlassian Jira (v8.20.10#820010)
