Vinod Kumar Vavilapalli updated MAPREDUCE-3035:
-----------------------------------------------
Status: Open (was: Patch Available)
Karam says that till now, hostname itself used to be of the form
rackid/hostname. So tools like Rumen also depend on this format.
I for one like the separate API and the history field. Let me talk to folks
taking care of Rumen.
Chackaravarthy, in the mean while, can you also dig up Rumen related details
(src/tools/org/apache/hadoop/tools/rumen/)? My feeling is you need to fix Rumen
either ways.
> MR V2 jobhistory does not contain rack information

> 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.
