> 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.
