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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
