[jira] [Commented] (YARN-4890) Unit test intermittent failure: TestNodeLabelContainerAllocation#testQueueUsedCapacitiesUpdate

    [ https://issues.apache.org/jira/browse/YARN-4890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15219441#comment-15219441 ] 

Bibin A Chundatt commented on YARN-4890:
----------------------------------------

IIUC NodeLabelsUpdateSchedulerEvent.NODE_LABELS_UPDATE event is yet to be processed. We are waiting for only node to be added not for completion of event processing.
{noformat}
    rm.registerNode("h4:1234", 10 * GB); // label = <empty>    
    waitSchedulerNodeJoined(rm, 4);
{noformat}
This could be the cause for random failures
