move tasks to another machine on the fly

[David Batista]

I get this error when running Reduce tasks on a machine:

java.lang.OutOfMemoryError: unable to create new native thread

        at org.apache.hadoop.mapred.ReduceTask$3.collect(ReduceTask.java:410)

is it possible to move a reduce task to other machine in the cluster on the fly?
