Subject [jira] [Updated] (MAPREDUCE-3398) Log Aggregation broken in Secure Mode
Date Sun, 11 Dec 2011 22:12:40 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3398?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mahadev konar updated MAPREDUCE-3398:
-------------------------------------

    Status: Open  (was: Patch Available)

@sid,
 The patch looks good. One minor nit, can you please add the config option in yarn-default.xml
and add a description to it? Also, do you have an open jira to document the whole logging
story? Accessing user logs and admin help for configuring them would be an important thing
to document.

> Log aggregation in secure mode does not work with MAPREDUCE-2977. The nodemanager relies
on the users credentials to write out logs to HDFS. These credentials are currently cancelled
once a job completes, before the NM can write out the logs.
