---------------------------------------
Summary: Issue with few /admin APIs when hit on PASSIVE Atlas
instance in HA mode
Key: ATLAS-4049
URL: https://issues.apache.org/jira/browse/ATLAS-4049
Project: Atlas
Issue Type: Bug
Components: atlas-core
Affects Versions: 2.1.0
Reporter: Umesh Padashetty
Atlas supports the following types of /admin APIs
# /version
# /audits
# /purge
# /metrics
# /status
# /export
# /import
# /patches
# /checkstate
# /activeSearches/\{id}
# /activeSearches
# /audit/\{auditGuid}/details
# /expimp/audit
# /server/\{serverName}
# /importfile
# /stack
# /session
Observing issues when these APIs are hit on PASSIVE Atlas instance in HA mode
Following APIs do not have any issue, when hit on ACTIVE or PASSIVE instance,
they produce the same output
# /version
# /status
# /session
# /stack
# /patches
# /activeSearches
# /activeSearches/\{id}
# /checkstate
But the following APIs have issue, when hit on the PASSIVE instance, they
either produce partial information, or they throw an ERROR.
* /audits

The case when an /admin API is hit on the PASSIVE instance, we should either
return a proper response, or we should redirect the request to the ACTIVE
instance. Providing partial information/error seems to be incorrect.
