Srikanth Kandula commented on YARN-2745:

[~vinodkv] Thanks for the related. The efforts are complementary. Indeed, 
adapting assignment based on the dynamic usage would be a good thing to have. 
This JIRA is more about packing based on anticipated usages as indicated by the 
ask. Dynamic packing would be even better.

> In this umbrella JIRA we propose an extension to existing scheduling 
> techniques, which accounts for all resources used by a task (CPU, memory, 
> disk, network) and it is able to achieve three competing objectives: 
> fairness, improve cluster utilization and reduces average job completion time.
