Robert Joseph Evans commented on MAPREDUCE-4721: ------------------------------------------------ I am fine with that for the UI, showing an N/A triggered by the -1, but the web services are returning that value too. We either need to update the documentation to indicate what a -1 means or switch it to do what the AM does. Sorry it has taken me so long to respond. > Task startup time in JHS is same as job startup time. > ----------------------------------------------------- > > Key: MAPREDUCE-4721 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4721 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: jobhistoryserver > Affects Versions: 0.23.3, 3.0.0, 2.0.2-alpha > Reporter: Ravi Prakash > Assignee: Ravi Prakash > Attachments: MAPREDUCE-4721.patch > > > As Bobby pointed out in > https://issues.apache.org/jira/browse/MAPREDUCE-4711?focusedCommentId=13471696&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13471696 > In the Map and Reduce tasks page, it should print the earliest task attempt > launch time as TaskImpl:getLaunchTime() does. -- This message is automatically generated by JIRA.
