------------------------------------
Hi [~curino], thanks for the review and potential bugs in this. This Jira turns
out to be a duplicate for YARN-6234, where people are still debating whether we
should create a new pipeline or reuse it for later attempts in the same node.
> Recreate interceptor chain for different attemptId in the same node in
> AMRMProxy

> In AMRMProxy, an interceptor chain is created per application attempt. But
> the pipeline mapping uses application Id as key. So when a different attempt
> comes in the same node, we need to recreate the interceptor chain for it,
> instead of using the existing one.
