[GitHub] [hadoop] cnauroth opened a new pull request, #5060: YARN-11360: Add number of decommissioning nodes to YARN cluster metrics.

cnauroth opened a new pull request, #5060:
URL: https://github.com/apache/hadoop/pull/5060

   ### Description of PR
   
   YARN cluster metrics expose counts of NodeManagers in various states including active and decommissioned. However, these metrics don't expose NodeManagers that are currently in the process of decommissioning. This can look a little spooky to a consumer of these metrics. First, the node drops out of the active count, so it seems like a node just vanished. Then, later (possibly hours later with consideration of graceful decommission), it comes back into existence in the decommissioned count.
   
   This issue tracks adding the decommissioning count to the metrics ResourceManager RPC. This also enables exposing it in the `yarn top` output. This metric is already visible through the REST API, so there isn't any change required there.
   
   ### How was this patch tested?
   
   The patch adds new unit tests for the ResourceManager RPC, correct merging of the metric through the router service and `yarn top`.
   
   ### For code changes:
   
   - [X] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
   - [X] Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
   - [X] If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under [ASF 2.0](http://www.apache.org/legal/resolved.html#category-a)?
   - [X] If applicable, have you updated the `LICENSE`, `LICENSE-binary`, `NOTICE-binary` files?

   > @slfan1989 , thanks for notifying me of the test failure! I gave +1 on your patch, but I'd also like to see one more code review from someone who has spent more time than me in the federation code.
   
   @cnauroth Thank you very much for your help reviewing the code!

   @mikaylakonst , as you suggested, I've updated the patch so that it also includes number of shutdown nodes.
   
   @abmodi , thank you for the review. FYI, I pushed up a change to add one more property after you approved.

   Regarding Checkstyle -0, TopCLI.java has 134 pre-existing Checkstyle violations. For consistency, my patch is continuing one of the class's patterns that triggers a Checkstyle violation. I'm not planning to address this right now. We could do a big style cleanup later, but I don't want to mix it with real logic changes here.
   
   Pre-commit tests also reported new compiler warnings, pasted below. I don't understand why this is happening. It looks unrelated to anything I'm changing in this patch, but I also can't reproduce the warnings locally.
