> When topology.node.switch.mapping.impl is set to enable rack-locality resolution via the topology script, from the RM web-UI, we can see the rack information for each node. Running a job also reveals the information about rack-local map tasks launched at end of job completion on the client side.
> But the hostname field for attempts in the JobHistory does not contain this rack information.
> In case of hadoop-0.20 securiy or MRV1, hostname field of job history does contain rackid/hostname whereas in MRV2, hostname field only contains the hostIP. Thus this is a regression.
