[jira] [Created] (YARN-10306) Create copy log aggregation file
controller
Adam Antal created YARN-10306:
---------------------------------
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.
