> Container Pooling in YARN
> -------------------------
>
> Key: YARN-5501
> URL: https://issues.apache.org/jira/browse/YARN-5501
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Arun Suresh
> Attachments: Container Pooling - one pager.pdf
>
>
> This JIRA proposes a method for reducing the container launch latency in
> YARN. It introduces a notion of pooling *Unattached Pre-Initialized
> Containers*.
> Proposal in brief:
> * Have a *Pre-Initialized Container Factory* service within the NM to create
> these unattached containers.
> * The NM would then advertise these containers as special resource types
> (this should be possible via YARN-3926).
> * When a start container request is received by the node manager for
> launching a container requesting this specific type of resource, it will take
> one of these unattached pre-initialized containers from the pool, and use it
> to service the container request.
> * Once the request is complete, the pre-initialized container would be
> released and ready to serve another request.
> This capability would help reduce container launch latencies and thereby
> allow for development of more interactive applications on YARN.
