Jayendra Parab updated ATLAS-4691:
----------------------------------
Description:
There is a discrepancy in the atlas debug metrics between the active and the
not active servers.
Steps to reproduce:
- Setup Atlas in HA mode with two instances of Atlas
- add "atlas.debug.metrics.enabled=true" to the Atlas configuration
(conf/atlas-application.properties)
- restart Atlas
- open Atlas and create a new entity (e.g. hdfs_path)
- check the debug metrics on both atlas instances using API call:
https://<atlas_host>:<atlas_port>/api/atlas/admin/debug/metrics
- The active instance returns correct metrics, whereas passive instance
returns empty metrics
The reason for this is that the debug metrics are maintained in-memory in the
active server. When "admin/debug/metrics" API call is accessed on the passive
server, the request isn't redirected to the active server like it does for the
other APIs, hence the passive node returns empty metrics.
