Subject [jira] [Updated] (MAPREDUCE-4005) AM container logs URL is broken for completed apps when log aggregation is enabled
Date Wed, 14 Mar 2012 18:30:40 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4005?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jason Lowe updated MAPREDUCE-4005:
----------------------------------

    Attachment: MAPREDUCE-4005.patch

Patch to add the application user to the AM container log URL.  In addition to the unit test,
verified with a single-node cluster that the AM container log URL worked for running and completed
applications when log aggregation was enabled and when it wasn't.

> With log aggregation enabled and yarn.log.server.url pointing to the job history server,
the AM container logs URL for a completed application fails with the error "Cannot get container
logs without an app owner".  Looking at the code in the nodemanager to handle redirects to
the log server, it appears the AM container log URL is missing a user name for the job.  I
verified that tacking on the app's user name after the AM container log URL reported by the
RM works.
