Siddharth Ahuja created YARN-10856: -------------------------------------- Summary: Prevent ATS v2 health check REST API call of ATS service itself is disabled. Key: YARN-10856 URL: https://issues.apache.org/jira/browse/YARN-10856 Project: Hadoop YARN Issue Type: Improvement Components: yarn-ui-v2 Affects Versions: 3.3.1 Reporter: Siddharth Ahuja
Currently, even if {{yarn.timeline-service.enabled}} is disabled, the UI2 code still goes ahead and performs timeline health check REST API calls, see [1], [2] and [3]. This is un-necessary and can cause slowness issues with RM UI2 page loading if a firewall is dropping packets on the ATS v2 port (as it is not meant to be available e.g. 8188/8190) in the background and the timeout is not yet hit. This ATSv2 health check REST API call is redundant and should be removed if the service itself is disabled.
