["Siddharth Seth (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TEZ-948?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Siddharth Seth updated TEZ-948:
-------------------------------

    Attachment: TEZ-948.1.txt

Patch logs counters at the end of the task, and occasionally during the lifetime of the task.
Adds some log messages to make it easy to figure out when a Shuffle completes, and added a counter to figure out how many source inputs were skipped because they were empty.

[~hitesh], review please.
