Sunil Govindan updated YARN-4901: --------------------------------- Summary: QueueMetrics needs to be cleared before MockRM is initialized (was: MockRM should clear the QueueMetrics when it starts) > QueueMetrics needs to be cleared before MockRM is initialized > ------------------------------------------------------------- > > Key: YARN-4901 > URL: https://issues.apache.org/jira/browse/YARN-4901 > Project: Hadoop YARN > Issue Type: Bug > Components: scheduler > Reporter: Daniel Templeton > Assignee: Peter Bacsko > Priority: Major > Attachments: YARN-4901-001.patch > > > The {{ResourceManager}} rightly assumes that when it starts, it's starting > from naught. The {{MockRM}}, however, violates that assumption. For > example, in {{TestNMReconnect}}, each test method creates a new {{MockRM}} > instance. The {{QueueMetrics.queueMetrics}} field is static, which means > that when multiple {{MockRM}} instances are created, the {{QueueMetrics}} > bleed over. Having the MockRM clear the {{QueueMetrics}} when it starts > should resolve the issue. I haven't looked yet at scope to see how hard easy > that is to do. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
