Srimanth Gunturi created YARN-1071: -------------------------------------- Summary: ResourceManager's decommissioned and lost node count is 0 after restart Key: YARN-1071 URL: https://issues.apache.org/jira/browse/YARN-1071 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Affects Versions: 2.1.0-beta Reporter: Srimanth Gunturi
I had 6 nodes in a cluster with 2 NMs stopped. Then I put a host into YARN's {{yarn.resourcemanager.nodes.exclude-path}}. After running {{yarn rmadmin -refreshNodes}}, RM's JMX correctly showed decommissioned node count: {noformat} "NumActiveNMs" : 3, "NumDecommissionedNMs" : 1, "NumLostNMs" : 2, "NumUnhealthyNMs" : 0, "NumRebootedNMs" : 0 {noformat} After restarting RM, the counts were shown as below in JMX. {noformat} "NumActiveNMs" : 3, "NumDecommissionedNMs" : 0, "NumLostNMs" : 0, "NumUnhealthyNMs" : 0, "NumRebootedNMs" : 0 {noformat} Notice that the lost and decommissioned NM counts are both 0. -- This message is automatically generated by JIRA.
