Kai Sasaki commented on YARN-4540: ---------------------------------- Sorry for misunderstanding. How can you put a log files without running jobs on YARN? Do you mean put or generate log files by yourself under "/hadoop/yarn/local"? My assumption is that you decreased "yarn.nodemanager.localizer.cache.target-size-mb" one by one. And caches were deleted under the target-size-mb correctly. But it takes more time than "yarn.nodemanger.localizer.cache.cleanup.interval-ms". Is it correct? > Yarn property "yarn.nodemanager.localizer.cache.cleanup.interval-ms" not > working as expected > -------------------------------------------------------------------------------------------- > > Key: YARN-4540 > URL: https://issues.apache.org/jira/browse/YARN-4540 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager, yarn > Affects Versions: 2.7.1 > Environment: Ambari – Version 2.1.2.1 > YARN - Version 2.7.1.2.3 > HDP - Version 2.3.2.0 > Reporter: Mark S > Priority: Minor > Original Estimate: 1h > Remaining Estimate: 1h > > I manually add specific YARN configuration to reduce my YARN cache size, > however it does not get updated for the interval specified by: > {code} > yarn.nodemanager.localizer.cache.cleanup.interval-ms > {code} > I did notice that eventually my server did reduce my YARN cache size over the > weekend. > h5.
