I have a 2 node cluster (each node having 32 GB RAM and 8 Cores). I have installed CDH 5.4.
But I dont think the available memory is being utilized by hadoop, as the page :8088/cluster/apps shows up only 16 GB in "Memory Total" column.
Only once I could see that the "Memory Total " as 64GB, not sure whats going on.
What could be the reason?

The yarn.nodemanager.resource.memory-mb parameter was set to 8GB which was causing the problem.
I have reset this to a higher value , which helped me resolve this behavior.
