Gagan commented on YARN-4037: ----------------------------- Hi Xuan, Yes I forgot to mention it, I did try to both in the yarn-site and mapred but couldn't get success either. I will retry with yarn-site. Could you tell me is the following value correct for <name>yarn.log.server.url</name> <value>localhost:jobhistory port</value> I think I might have put in the incorrect port earlier. What would be the correct port to put in and where to get it from ? Also when I googled about this error, one of the links mentioned the creation of stderr file, where is it created ? > Hadoop - failed redirect for container > -------------------------------------- > > Key: YARN-4037 > URL: https://issues.apache.org/jira/browse/YARN-4037 > Project: Hadoop YARN > Issue Type: Bug > Components: yarn > Affects Versions: 2.7.1 > Environment: Windows 7, Apache Hadoop 2.7.1 > Reporter: Gagan > > I believe this issue has been addressed earlier in > https://issues.apache.org/jira/browse/YARN-1473 though I am not sure because > the description of the JIRA does not talk about the following message > Failed while trying to construct the redirect url to the log server. Log > Server url may not be configured > java.lang.Exception: Unknown container. Container either has not started or > has already completed or doesn't belong to this node at all. > Could some one look at the same and provide detail on the root cause and > resolution ? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
