             Summary: [SCM HA Security] Handle leader changes between SCMInfo and getSCMSigned Cert in OM
                 Key: HDDS-5052
                 URL: https://issues.apache.org/jira/browse/HDDS-5052
             Project: Apache Ozone
          Issue Type: Bug
            Reporter: Bharat Viswanadham
            Assignee: Bharat Viswanadham


This Jira is to handle leader change between getScmInfo and getScmSignedCert.

*Problem:*
ScmInfo returns the leader SCMID

getSCMSignedCert, during generate certificate it has a check compare the scmId passed in CSR, is same as current SCM scmID

In this case when the leader change between these 2 calls OM will fail to get a Certificate.

*Proposed Solution:*
getScmInfo returns primary SCM ID, and OM can pass this Primary SCM ID in CSR.
In this way, even if the leader changes OM can still get a certificate.

Note: primary SCM Id is the same across the SCM HA quorum nodes.
