Varun Saxena commented on YARN-4330: ------------------------------------ Yes they are unrelated. We have already have JIRAs' for these failures. > MiniYARNCluster is showing 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 > Assignee: Varun Saxena > Priority: Blocker > Labels: oct16-hard > Attachments: YARN-4330.002.patch, YARN-4330.003.patch, > YARN-4330.01.patch > > > 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) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
