> Key: HDDS-5317
> URL: https://issues.apache.org/jira/browse/HDDS-5317
> Project: Apache Ozone
> Issue Type: Bug
> Components: SCM HA, Security
> Reporter: Bharat Viswanadham
> Assignee: Bharat Viswanadham
> Priority: Blocker
>
> GetSCMCertificate can happen non-leader SCM, as rootCA is only run on primary
> SCM.
> So, when an SCM is bootstrapped, let's say it connects first to a
> bootstrapped SCM, we fail with a SCMSecurityResponse with status set to
> NOT_A_PRIMARY_SCM. As we return with a response, failOver will not happen.
> *SCMSecurityProtocolClientSideTranslatorPB*
> {code:java}
> private SCMSecurityResponse handleError(SCMSecurityResponse resp)
> throws SCMSecurityException {
> if (resp.getStatus() != SCMSecurityProtocolProtos.Status.OK) {
> throw new SCMSecurityException(resp.getMessage(),
>
> SCMSecurityException.ErrorCode.values()[resp.getStatus().ordinal()]);
> }
> return resp;
> }
> {code}
> To solve this issue, one possible solution is on server check if it is
> SCMSecurityException with errorCode NOT_A_PRIMARY_SCM return a
> RetriableWithFailOverException. In this way, FailOverProxyProvider performs
> failOver and Retry to the next SCM.
