Yan created YARN-7267:
-------------------------
Summary: Container should also return container system status to
Application Master
Key: YARN-7267
URL: https://issues.apache.org/jira/browse/YARN-7267
Project: Hadoop YARN
Issue Type: Improvement
Components: api
Reporter: Yan
Priority: Minor
Currently the container exit status is in the form of ContainerExitStatus,
where only 9 failure status codes are available. However there could be many
system error codes as result of launching a container shell command, or a set
of such commands. It's desirable that this system code be propagated to AM, in
addition to the 9 status codes that appear to result from YARN actions.
One use case is that a necessary application resource is absent on a node to
launch a container command. A "file not found" status would have provided
enough info for AM to take some corrective action before a retry attempt.
