Thanks for replying Harsh.

So, it means that in my case of configuration, *mapred.child.java.opts -Xmx1g* will be avoided completely and *mapred.map.child.java.opts -Xmx2g*will be considered for map tasks and
* mapred.reduce.child.java.opts = -Xmx512m* will be considered for reduce
tasks. Right?

Thanks,
Gaurav
