Robert Joseph Evans created YARN-221:
----------------------------------------

             Summary: NM should provide a way for AM to tell it not to aggregate logs.
                 Key: YARN-221
                 URL: https://issues.apache.org/jira/browse/YARN-221
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: nodemanager
    Affects Versions: 0.23.4
            Reporter: Robert Joseph Evans


The NodeManager should provide a way for an AM to tell it that either the logs should not
be aggregated, that they should be aggregated with a high priority, or that they should be
aggregated but with a lower priority.  The AM should be able to do this in the ContainerLaunch
context to provide a default value, but should also be able to update the value when the container
is released.

This would allow for the NM to not aggregate logs in some cases, and avoid connection to the
NN at all.
