Steve Loughran created YARN-4774: ------------------------------------ Summary: ATS can block in shutdown under heavy load Key: YARN-4774 URL: https://issues.apache.org/jira/browse/YARN-4774 Project: Hadoop YARN Issue Type: Bug Components: timelineserver, webapp Affects Versions: 2.8.0 Reporter: Steve Loughran Priority: Minor
seen in scale test teardown, ATS blocked in shutdown for some time; stack trace implies that jetty was waiting for threads to finish. Hypothesis: the scale of the data being retrieved in a GET was large enough that the jetty worker threads weren't completing the operations, so blocking the {{stop()}} operation until they finally finished. There is support in Jetty for a max shutdown time; this just isn't configured in YARN. It could be configured, and then ATS & other services could customise it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
