-----------------------------
Summary: 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. Does
it make sense?
