Date Thu, 20 Oct 2011 12:43:10 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3230?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli updated MAPREDUCE-3230:
-----------------------------------------------

    Description: 
Size of cluster is 350 NMs. I have topology.node.switch.mapping.impl set to enable rack-locality.
Ran randomwriter/sort and scan jobs. Both jobs ran completed successfully.

On Job client sort job says :
{code}
Launched map tasks=16800
Launched reduce tasks=700
Other local map tasks=10
Rack-local map tasks=16790
{code}

JobHistory files also don't have information about Data Local Maps.

There used to be information about data local maps before, till about a month back, like so:

For sort with 349 NMs :
{code}
Launched map tasks=16754 
Launched reduce tasks=700
Other local map tasks=48
Data-local map tasks=16459
Rack-local map tasks=248
{code}

  was:
Size of cluster is 350 NMs.
I have topology.node.switch.mapping.impl is set to enable rack-locality. 
Ran randomwriter/sort and scan jobs.
Both jobs ran 
Launched map tasks=16800

On Job client sort says -:
  Launched map tasks=16800
  Launched reduce tasks=700
  Other local map tasks=10
  Rack-local map tasks=16790

On Job client scan says -:
  Launched map tasks=16800
  Other local map tasks=50
  Rack-local map tasks=16750

JobHistory files also does having information of Data Local Maps

There is information data local maps, last month, when I checked out code branch-0.23
data local maps was coming
e.g.
For sort it was with 349 NMs-:
  Launched map tasks=16754 
  Launched reduce tasks=700
  Other local map tasks=48
  Data-local map tasks=16459
  Rack-local map tasks=248

For scan it was with 349 NMs -:
  Launched map tasks=16752
  Other local map tasks=27
  Data-local map tasks=16532
  Rack-local map tasks=193




        Summary: No information about Data Local maps from Job client CLI and in JobHistory
  (was: Data Local maps information not coming  on Job client CLI or in JobHistory )

Thanks for filing this, Karam!
