Arun C Murthy commented on MAPREDUCE-3035: ------------------------------------------ Hi Chackaravarthy, any update on this? Thanks. > MR V2 jobhistory does not contain rack information > -------------------------------------------------- > > 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: Blocker > Fix For: 0.23.0 > > Attachments: 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. -- This message is automatically generated by JIRA.
