Truong Duc Kien created FLINK-8949: -------------------------------------- Summary: Rest API failure with long URL Key: FLINK-8949 URL: https://issues.apache.org/jira/browse/FLINK-8949 Project: Flink Issue Type: Bug Components: REST, Webfrontend Affects Versions: 1.4.2 Reporter: Truong Duc Kien
When you have jobs with high parallelism, the URL for a REST request can get very long. When the URL is longer than 4096 bytes, the REST API will return error {{Failure: 404 Not Found}} This can easily be seen in the Web UI, when Flink queries for the watermark using the REST API: {{GET /jobs/:jobId/vertices/:vertexId/metrics?get=0.currentLowWatermark,1.currentLowWatermark,2.currentLo...}} The request will fail with more than 170 subtasks and the watermark will not be displayed in the Web UI. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
