Devaraj K commented on YARN-5764:
---------------------------------
Thanks [[email protected]] for the review.
bq. I see commented code in the body of the function and also in the unit tests.
I commented the recovery code and related tests code since the YARN-7033 was
not committed by the time when the patch created.
bq. is package-info.java necessary?
It is necessary and it adds a checkstyle error if we don't have it.
I will update the patch with the comments fixed and uncommented code.

> The purpose of this feature is to improve Hadoop performance by minimizing
> costly remote memory accesses on non SMP systems. Yarn containers, on launch,
> will be pinned to a specific NUMA node and all subsequent memory allocations
> will be served by the same node, reducing remote memory accesses. The current
> default behavior is to spread memory across all NUMA nodes.
