Hudson commented on MAPREDUCE-3035:
-----------------------------------
Integrated in Hadoop-Hdfs-0.23-Build #58 (See [https://builds.apache.org/job/Hadoop-Hdfs-0.23-Build/58/])

> Key: MAPREDUCE-3035
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3035
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Karam Singh
> Assignee: chackaravarthy
> Priority: Critical
> Fix For: 0.23.0
>
> Attachments: MAPREDUCE-3035-1.patch, MAPREDUCE-3035-20111031.1.txt, MAPREDUCE-3035.patch

>
> 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.
