Summary: Flaky test TestTaskAttempt#testReducerCustomResourceTypes Key: MAPREDUCE-7064 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7064 Project: Hadoop Map/Reduce Issue Type: Bug Components: client, test Reporter: Peter Bacsko Assignee: Peter Bacsko The test {{TestTaskAttempt#testReducerCustomResourceType}} can occasionally fail with the following error: {noformat} org.apache.hadoop.yarn.exceptions.ResourceNotFoundException: Unknown resource 'a-custom-resource'. Known resources are [name: memory-mb, units: Mi, type: COUNTABLE, value: 0, minimum allocation: 0, maximum allocation: 9223372036854775807, name: vcores, units: , type: COUNTABLE, value: 0, minimum allocation: 0, maximum allocation: 9223372036854775807] at org.apache.hadoop.mapreduce.v2.app.job.impl.TestTaskAttempt.createReduceTaskAttemptImplForTest(TestTaskAttempt.java:434) at org.apache.hadoop.mapreduce.v2.app.job.impl.TestTaskAttempt.testReducerCustomResourceTypes(TestTaskAttempt.java:1535) {noformat} The root cause seems to be an interference from previous tests that start instance(s) of {{FailingAttemptsMRApp}} or {{FailingAttemptsDuringAssignedMRApp}}. When I disabled these tests, {{testReducerCustomResourceTypes}} always passed. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
