Subject Different ways of configuring the memory to the TaskTracker child process (Mapper and Reduce Tasks)
Date Sun, 06 Nov 2011 15:17:20 GMT
Hi,

What is the difference between setting the mapred.job.map.memory.mb and
mapred.child.java.opts using -Xmx to control the maximum memory used by a
Mapper and Reduce task? Which one takes precedence?

Thanks,
Praveen
