----------------------------------------
Summary: archive-logs tool changes log ownership to the Yarn user
when using DefaultContainerExecutor
Key: MAPREDUCE-6550
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6550
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 2.8.0
Reporter: Robert Kanter
Assignee: Robert Kanter
The archive-logs tool added in MAPREDUCE-6415 leverages the Distributed Shell
app. When using the DistributedContainerExecutor, this means that the job will
actually run as the Yarn user, so the resulting har files are owned by the Yarn
user instead of the original owner. The permissions are also now
world-readable.
In the below example, the archived logs are owned by 'yarn' instead of 'paul'
and are now world-readable:
