[jira] [Commented] (MAPREDUCE-3317) Rumen TraceBuilder is emiting null as hostname

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13140873#comment-13140873 ] 

Ravi Gummadi commented on MAPREDUCE-3317:
-----------------------------------------

LoggedTaskAttempt.setHostName() has a minor bug. It is checking if this.rackName is null or not instead of checking the parameter rackName.
