Subject RE: Map Reduce in heterogeneous environ..

It is possible to use MapReduce on heterogeneous environment without any
extra interface. If hard disk capacity is different, then extra capacity
will be added in hdfs and if more memory is present then depending on
the task requirement it will be used.

No. of slots per task tracker cannot be varied so even if some nodes
have additional cores, extra slots cannot be added.
