             Summary: Create copy log aggregation file controller
                 Key: YARN-10306
                 URL: https://issues.apache.org/jira/browse/YARN-10306
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: yarn
    Affects Versions: 3.3.0
            Reporter: Adam Antal
            Assignee: Adam Antal


Log aggregation file controllers were created (YARN-6875) to effectively wrap 
and move the logs of containers to a remote filesystem. While this filesystem 
was HDFS, it was logical to create as big files as we can by packing it into an 
aggregated (blob) file. As S3A is a valid target since YARN-9525, it is much 
less painful from the end user point of view to browse these files as they are 
- and not in an aggregated blob format.

I propose to implement a "dumb"/bare copy file controller that copies the 
container log files to the remote file system without any aggregation/wrapping. 
The only thing which makes sense to enable is the compression of those files, 
so we should support that.
