This will happen when we consecutively restart the same NM twice: > * NM started at port 10001 > * NM restarted at port 10002 > * NM restarted at port 10003 > * NM:10001 timeout, {{ClusterMetrics#incrNumLostNMs()}}, # lost node=1; > {{rmNode.context.getInactiveRMNodes().put(rmNode.nodeId.getHost(), rmNode)}}, > {{inactiveNodes}} has 1 element > * NM:10002 timeout, {{ClusterMetrics#incrNumLostNMs()}}, # lost node=2; > {{rmNode.context.getInactiveRMNodes().put(rmNode.nodeId.getHost(), rmNode)}}, > {{inactiveNodes}} still has 1 element > Since we allow multiple NodeManagers on one host (as discussed in YARN-1888), > {{inactiveNodes}} should be of type {{ConcurrentMap<NodeId, RMNode>}}. If > this will break the current API, then the key string should include the NM's > port as well. > Thoughts? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
