    [ https://issues.apache.org/jira/browse/TEZ-568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13799327#comment-13799327 ] 

Bikas Saha commented on TEZ-568:
--------------------------------

Should this be done via counters? the AM already writes out some counters to the history logs e.g. read/write counters.

> The AM can include this information in the history logs, which allows for much easier analysis of job performance.
> As an example, shuffle reporting completion time, Tez itself reporting initialization time etc.
