Rohith created YARN-3222: ---------------------------- Summary: RMNodeImpl#ReconnectNodeTransition should send scheduler events in sequential order Key: YARN-3222 URL: https://issues.apache.org/jira/browse/YARN-3222 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Affects Versions: 2.6.0 Reporter: Rohith Assignee: Rohith Priority: Critical
When a node is reconnected,RMNodeImpl#ReconnectNodeTransition notifies the scheduler in a events node_added,node_removed or node_resource_update. These events should be notified in an sequential order i.e node_added event and next node_resource_update events. But if the node is reconnected with different http port, the oder of scheduler events are node_removed --> node_resource_update --> node_added which causes scheduler does not find the node and throw NPE and RM exit. Node_Resource_update event should be always should be triggered via RMNodeEventType.RESOURCE_UPDATE -- This message was sent by Atlassian JIRA (v6.3.4#6332)
