Vinod Kumar Vavilapalli updated MAPREDUCE-3035:
-----------------------------------------------
Description:
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.
