Wangda Tan updated YARN-5270:
-----------------------------
    Attachment: YARN-5270-branch-2.001.patch

Thanks [~kasha],

[~sseth] offline mentioned that YARN-4844 breaks binary compatibility as well, according to
Java compatibility doc, change parameter types in signature causes method cannot find issue.
That means if we run a YARN application compiled against Hadoop 2.7 in a Hadoop 2.8 deployment,
it fails.

What I have done in this patch:
- Added {{long getMemorySize}} and kept {{int getMemory}}
- Removed {{long getVirtualCoresSize}} and kept {{int setVirtualCores}}
- Other changes like wrong type converting issues in Resources class.
