----------------------------------
Summary: Giving Yarn Application the Option to Black Out Certain
Nodes On the Fly
Key: YARN-7256
URL: https://issues.apache.org/jira/browse/YARN-7256
Project: Hadoop YARN
Issue Type: New Feature
Components: applications
Reporter: Tanping Wang
Priority: Minor
The application should have the option to block out certain "bad" nodes at run
time. A use case is that if the tasks of an application fail on a particular
node multiple times, the application should be able to add the "bad" node to
the "blacklist" for this application. As the result, no other tasks of this
application will be launched to the same node at run time.
