Jonathan Hung commented on HADOOP-12825:
----------------------------------------
[~shv] it seems this was never committed to branch-2.7 but the fix version was
set to 2.7.2. I attached a branch-2.7 patch. Can we get this committed? Thanks!

> Logging slow name resolutions would be useful in identifying DNS performance
> issues in a cluster. Most resolutions go through
> {{org.apache.hadoop.security.SecurityUtil.getByName}} ( see attached call
> graph ). Adding additional logging to this method would expose such issues.
