HBASE-27814 Add support for dump and process metrics servlet in REST … #5215

NihalJain · 2023-05-03T12:07:47Z

…InfoServer

Other changes:

Ensure info server stops during stop()
Extract header and footer. This would fix the log level page layout for rest web UI (See HBASE-20693)
Add hostname in the landing page instead of just port similar to other web UIs

NihalJain · 2023-05-03T12:22:15Z

Started a local cluster and started HBase REST server.

Verified the landing page has the right page title, all the tabs are visible, hostname is displayed instead of portnumber and no error in page rendering.
- Before Patch:
- After Patch
Verified /logLevel page is fixed with appropriate tabs, as expected and shown in HBASE-20693
- Before Patch:
- After Patch
Verified newly added http://localhost:9093/processRest.jsp works as expected

Verified newly added http://localhost:9093/dump page works as expected

Sample page output

REST Server status for SOME_HOSTNAME,9092,1683113342961 as of Wed May 03 17:05:00 IST 2023

Verified all other pages like /logs, /jmx, /conf works as before

Also tried the patch on a real cluster by building against 2.5.x and verified above points.

Hi could someone please have a look at this, if familiar with REST web UI related code? I have attached screenshots post testing in the PR as well.

Just some minor comments. Nice addition. Sorry to keep you waiting on the review.

I will rebase the code, re run all tests locally and if no issues found, will push this change as is tomorrow.

Action items based on review: https://issues.apache.org/jira/browse/HBASE-28300, https://issues.apache.org/jira/browse/HBASE-28299 will be taken up as follow up.

Started a local cluster and started HBase REST server.

Verified the landing page has the right page title, all the tabs are visible, hostname is displayed instead of portnumber and no error in page rendering.
- Before Patch:
- After Patch
Verified /logLevel page is fixed with appropriate tabs, as expected and shown in HBASE-20693
- Before Patch:
- After Patch
Verified newly added http://localhost:9093/processRest.jsp works as expected

Verified newly added http://localhost:9093/dump page works as expected

Sample page output

REST Server status for SOME_HOSTNAME,9092,1683113342961 as of Wed May 03 17:05:00 IST 2023

Verified all other pages like /logs, /jmx, /conf works as before

Also tried the patch on a real cluster by building against 2.5.x and verified above points.

Reverfied all of this. I also wrote a simple postman collection for basic CRUD test for REST at https://gist.github.com/NihalJain/7db91823bd140e41953a88eb3df56eae

Can we keep this inside test resources of hbase REST? Might be useful for others as well. Please let me know what you think.

@bbeaudreault please let me know if you want this in 2.6.

You mean keep the postman config definition? Can it be used for an automated testing? I've used postman before, for API development and manual testing, but I've never tried to wire it up to a maven test phase. I am in favor of improving our test coverage if it's lacking.

Thanks a lot for seeing this one through, and for taking the time to file follow-up issues !

@bbeaudreault please let me know if you want this in 2.6.

I will pull this in branch-2.6, it is unreleased yet. And its best to keep code in sync in branch-2.6+. Also I plan to do more fixes around this in future (for eg @ndimiduk review comments), all of which may go over same code and hence we would have to skip them for branch-2.6, which is a bad idea.
