Jiandan Yang commented on YARN-5636: ------------------------------------- [~Tao Jie] I think you solution is good. You can provide a patch to review. > Support reserving resources on certain nodes for certain applications > --------------------------------------------------------------------- > > Key: YARN-5636 > URL: https://issues.apache.org/jira/browse/YARN-5636 > Project: Hadoop YARN > Issue Type: Improvement > Components: scheduler > Reporter: Tao Jie > > We have met such circumstance: > We are trying to run storm&kafka on yarn by Slider, and Storm&Kafka writes > data to local disk on node. If some containers or the application fails, we > expect that those containers would restart on the same node as they run > before, otherwise data written on local would lost. > For slider, it will trying to ensure restarted container on same nodes as > before. However for yarn, resource may be assigned to other applications when > former long-running application is down. > As a result we'd better to have a mechanism that reserve some resource for > certain long-running applications on certain nodes for a period of time.
