> Application1 has a demand of 8GB[Map Task Size as 8GB] which is more than Node_1 can handle.
> Node_1 has a size of 8GB and 2GB is used by Application1's AM.
> Hence reservation happened for remaining 6GB in Node_1 by Application1.
> A new job is submitted with 2GB AM size and 2GB task size with only 2 Maps to run.
> Node_2 also has 8GB capability.
> But Application2's AM cannot be launched in Node_2. And Application2 waits longer as only 2 Nodes are available in cluster.
