Subject [jira] [Updated] (MAPREDUCE-2989) JobHistory should link to task logs
Date Sun, 23 Oct 2011 09:12:32 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2989?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.
