Balancer's Java Heap Size in bytes.
HttpFS's Java Heap Size in bytes.
Failover Controller's Java Heap Size in bytes.
MapReduce Child Java Maximum Heap Size
Reduce Task Maximum Heap Siz
TaskTracker's Java Heap Size in bytes.

When i start my cluster these guys occupy the large number of memory, Best
