[jira] [Commented] (TEZ-887) Allow counters to be separated at a per Input/Output level

    [ https://issues.apache.org/jira/browse/TEZ-887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13915070#comment-13915070 ] 

Bikas Saha commented on TEZ-887:
--------------------------------

Do we agree that we need to revert this patch in favor of separating counters within the framework instead of by user name in the short to medium term? This jira breaks anyone who writes their own inputs/outputs and uses their own counters.

Other than that, we patch itself looks ok.

> Counters generated by various Inputs / Outputs are aggregated across all I/Os belonging to a task which reduces their usefulness.
