      Description

      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.
