["Gopal V (JIRA)" <ji...@apache.org>]

Gopal V commented on TEZ-1738:
------------------------------

[~rajesh.balamohan]: LGTM - +1.

This is not built as part of the regular maven build and the use of this is upto a sufficiently motivated developer. Changes to PIG's UDF implementation does not affect the tez primary build.

> It can be time consuming to download logs via "yarn logs -applicationId <appId> | grep something".  Also mining large volumes of logs can be time consuming on single node.
> A simple pigloader would be useful to have in tez-tools which can parse TFiles and provide line by line format (tuple of (machine, key, line)) for distributed processing of logs.
