> 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.
