Amar Kamat commented on MAPREDUCE-3349:
---------------------------------------
Kindly make sure that Rumen's {{TopologyBuilder}} is also fixed in this JIRA.
{{TopologyBuilder}} expects hostname in the form '/rack/host' and uses
{{TaskAttemptFinishedEvent}} and {{TaskAttemptUnsuccessfulCompletionEvent}} for
the same. It also uses split-location from {{TaskStartedEvent}}. Since the
hostnames and racknames are now separately logged, we need to make sure that
{{TopologyBuilder}} is aware of that.
> No rack-name logged in JobHistory for unsuccessful tasks
