Subject [jira] [Commented] (MAPREDUCE-3744) Unable to retrieve application logs via "yarn logs" or "mapred job -logs"
Date Fri, 27 Jan 2012 22:26:11 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13195155#comment-13195155

Jason Lowe commented on MAPREDUCE-3744:

Comment race.  It acts differently when the server address is configured in that it tries
to access an HDFS path, but the path isn't the same as with "yarn logs" and it still fails.
