Ming Ma updated YARN-221:
-------------------------
Attachment: YARN-221-trunk-v2.patch
Here is the patch to support log aggregation sampling at yarn layer. Yarn
applications can choose to override the default behavior. Without any change at
MR layer to specify per-container log aggregation policy, yarn log aggregation
sampling policy at cluster level will be applied.
> NM should provide a way for AM to tell it not to aggregate logs.

> 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.
