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 :

Launched map tasks=16800
Launched reduce tasks=700
Other local map tasks=10
Rack-local map tasks=16790

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 :

Launched map tasks=16754 
Launched reduce tasks=700
Other local map tasks=48
Data-local map tasks=16459
Rack-local map tasks=248
