Brandon Scheller created YARN-9088: -------------------------------------- Summary: Non-exclusive labels break QueueMetrics Key: YARN-9088 URL: https://issues.apache.org/jira/browse/YARN-9088 Project: Hadoop YARN Issue Type: Bug Components: capacity scheduler, resourcemanager Affects Versions: 2.8.5 Reporter: Brandon Scheller
QueueMetrics are broken (random/negative values) when non-exclusive labels are being used and unlabeled containers run on labeled nodes. This is caused by the change in the patch here: https://issues.apache.org/jira/browse/YARN-6467 It assumes that a container's label will be the same as the node's label that it is running on. If you look within the patch, sometimes metrics are updated using the request.getNodeLabelExpression(). And sometimes they are updated using node.getPartition(). This means that in the case where the node is labeled while the request isn't, these metrics only get updated when referring to the default queue. This stops metrics from balancing out and results in incorrect and negative values in QueueMetrics. -- 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
