> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: tools/rumen
> Affects Versions: 0.23.0
> Reporter: Karam Singh
> Assignee: Amar Kamat
> Priority: Blocker
>
> After MAPREDUCE-3035 and MAPREDUCE-3317
> Now MRV2 job history contains hostName and rackName.
> when rumen trace builder is ran on jobhistory, its generated trace contains hostname in form of
> hostName : /raclname/hostname
> But getHostName for LoggedTaskAttempt returns hostname as null
> Seems that TraceBuilder is setting hostName properly but JobTraceReader is not able read it.
