During making the code patch for YARN-8059, I come across a flaky test, see this link: https://builds.apache.org/job/PreCommit-YARN-Build/22412/artifact/out/patch-unit-hadoop-yarn-project_hadoop-yarn_hadoop-yarn-server_hadoop-yarn-server-resourcemanager.txt This is the error message: {code:java} [ERROR] Tests run: 108, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 19.37 s <<< FAILURE! - in org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.TestFairScheduler [ERROR] testChildMaxResources(org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.TestFairScheduler) Time elapsed: 0.164 s <<< FAILURE! java.lang.AssertionError: App 1 is not running with the correct number of containers expected:<2> but was:<0> at org.junit.Assert.fail(Assert.java:88){code} So the thing is, even if we had 8 node updates, due to the nature of how we handle the events, it can happen that no container is allocated for the application. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
