Steve Loughran created YARN-4330: ------------------------------------ Summary: MiniYARNCluster prints multiple Failed to instantiate default resource calculator warning messages Key: YARN-4330 URL: https://issues.apache.org/jira/browse/YARN-4330 Project: Hadoop YARN Issue Type: Bug Components: test, yarn Affects Versions: 2.8.0 Environment: OSX, JUnit Reporter: Steve Loughran Priority: Blocker
Whenever I try to start a MiniYARNCluster on Branch-2 (commit #0b61cca), I see multiple stack traces warning me that a resource calculator plugin could not be created {code} (ResourceCalculatorPlugin.java:getResourceCalculatorPlugin(184)) - java.lang.UnsupportedOperationException: Could not determine OS: Failed to instantiate default resource calculator. java.lang.UnsupportedOperationException: Could not determine OS {code} This is a minicluster. It doesn't need resource calculation. It certainly doesn't need test logs being cluttered with even more stack traces which will only generate false alarms about tests failing. There needs to be a way to turn this off, and the minicluster should have it that way by default. Being ruthless and marking as a blocker, because its a fairly major regression for anyone testing with the minicluster. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
