Íñigo Goiri commented on YARN-9782: ----------------------------------- TestAMSimulator is a little suspicious. In the new test testEnableCaching(), we should also test the reverse (DNS_CACHING_ENABLED set to false). > Avoid DNS resolution while running SLS. > --------------------------------------- > > Key: YARN-9782 > URL: https://issues.apache.org/jira/browse/YARN-9782 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Abhishek Modi > Assignee: Abhishek Modi > Priority: Major > Attachments: YARN-9782.001.patch, YARN-9782.002.patch > > > In SLS, we add nodes with random names and rack. DNS resolution of these > nodes takes around 2 seconds because it will timeout after that. This makes > the result of SLS unreliable and adds spikes. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
