Siddharth Seth updated MAPREDUCE-2989:
--------------------------------------

    Attachment: MR2989_v2.txt

Revised patch.

- Changed log aggregation to work with per user dirs. (Should've really been a 
separate jira instead of bloating this patch)
- Moved AggregatedLogsBlock to the NodeManager
- The NM doesn't really need a redirect since containers aren't available as 
soon as they finish. Log aggregation is only complete after the app finishes. 
Changed ContainerLogsPage to pull logs from the local disk while the app is 
alive. There's a redirect there for the case where an app finishes while a user 
is viewing a container log.
- Added a default YARN_ACL = " ", used when an AppMaster doesn't provide any.
- This iteration has aggregation enabled.

> The log link on the task attempt page is currently broken - since it relies 
> on a ContainerId. We should either pass the containerId via a history event - 
> or some kind of field with information about the log location.
