------------------------------------
Summary: RM to bind and notify a restarted AM of existing
containers
Key: YARN-1041
URL: https://issues.apache.org/jira/browse/YARN-1041
Project: Hadoop YARN
Issue Type: Sub-task
Components: resourcemanager
Affects Versions: 3.0.0
Reporter: Steve Loughran
For long lived containers we don't want the AM to be a SPOF.
When the RM restarts a (failed) AM, it should be given the list of containers
it had already been allocated. the AM should then be able to contact the NMs to
get details on them. NMs would also need to do any binding of the containers
needed to handle a moved/restarted AM.
