> 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.
> The exception message is available in comments.
