[jira] [Commented] (TEZ-2121) INPUT_BYTES counter to describe amount of data read by a task

["Robert Grandl (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TEZ-2121?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14328164#comment-14328164 ] 

Robert Grandl commented on TEZ-2121:
------------------------------------

Srikanth Kandula and I propose to add a new INPUT_BYTES counter in order to account for the amount of data being read by a task in a vertex. We observe that similar counter exists for data being written.

We also submit a patch for the new counter.
