Hitesh Sharma updated YARN-5501: -------------------------------- Attachment: Container Pooling - one pager.pdf > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
