[jira] [Commented] (YARN-6234) Support multiple attempts on the
node when AMRMProxy is enabled

I added the NPE check, and I double checked and I noticed we don't need a finally block to ensure we leave things tidy since it is already handled in the code.

> Currently {{AMRMProxy}} initializes an interceptor chain pipeline for every active AM in the node but it doesn't clean up & reinitialize correctly if there's a second attempt for any AM in the same node. This jira is to track the changes required to support multiple attempts on the node when AMRMProxy is enabled.
