> Several tasks will be achieved in this JIRA based on the demo patch in MAPREDUCE-6608:
> 1. AM discovery base on YARN register service. Could be replaced by YARN-4758 later due to scale up issue.
> 2. Retry logic for TaskUmbilicalProtocol RPC connection
> 3. In-flight task recover after AM restart via JHS
> 4. Configuration to control the behavior compatible with previous when not enable this feature (by default).
> All security related issues and other concerns discussed in MAPREDUCE-6608 will be addressed in follow up JIRAs.
