Gera Shegalov commented on MAPREDUCE-5696:
------------------------------------------
[~hitesh], I think we can move these few YARN changes to YARN-1529 instead of
creating a new JIRA. I'll upload new patch versions.

> Users are often unaware of localization cost that their jobs incur. To
> measure effectiveness of localization caches it is necessary to expose the
> overhead in the form of user-visible metrics. The purpose of this JIRA is to
> compliment YARN-1529. While YARN-1529 attempts to provide a cluster-wide view
> to cluster admins, this JIRA focuses on exposing the localization overhead on
> per-job basis to the job owner/user.
