Hean-Chhinling · 2025-12-09T16:52:46Z

Description of PR

Add two new endpoints to ease the process of collecting JStack for running Application and Node.

{nm_address}/ws/v1/node/apps/{app_id}/jstack
{nm_address}/ws/v1/node/jstack

How was this patch tested?

Manually tested.

application_jstack_response.txt.rtf

NodeManager_Jstack_Shell.txt

when set nodemanager.jstack-endpoints.enabled = false;

For code changes:

Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?

I think diagnostic-api instead of jstack-endpoints would be more suitable here.

hmmm...since this configuration only control the jstack endpoints, so I think it is better to name it jstack instead of diagnostic.

May I know why do you want to name it diagnostic-api?

It seems to general to me.

If later someone would like to add other functionality to the endpoint a more generic name can be useful here.

but yes, based on the property desc we can keep as it is

Okay, i see your point. I will keep it as it is since this is only for the jstack maybe in the future a new configuration shall be added or refactored to combine both together maybe jmap or something.

.../src/main/java/org/apache/hadoop/yarn/server/nodemanager/webapp/DiagnosticJStackService.java

…default jstack endpoint to false

All the endpoints failed with 404 as of now. Not sure why this is happening

Maybe of not running with the up-to-date hadoop build

Next step is to create unit-test for DiagnosticJstackService class:

Check the applicationId, wrong format
Test on getting the Process ID for specific applicationId
Test when running jstack command on a ProcessId then the process is not alive anymore

+        .filter(childProcess -> childProcess.info().command().orElse("").contains("java"))


Now only java based container checked with jstack what is good.
However now if a container is not java proc, and user wants to debug it with the API, the container wont be present in the response what can be confusing.
Instead if skipping non java based containers, can you please add them to the response and marked them there like not java containers so jstack can not be done for them?

Good idea, i will put those non-java container in the response.

also maybe there is a more robust way to check what is java process:

can you please check this?
