Aswin Shakil commented on HDDS-10760:
-------------------------------------
This error occurs because the SCMException is thrown as RemoteException to the
Client ({{StorageContainerLocationProtocolClientSideTranslatorPB}}) from the
server side ({{StorageContainerLocationProtocolServerSideTranslatorPB}}). We
unwrap the exception using {{RemoteException#unwrapRemoteException()}}. This
function expects a constructor with {{String.class}} parameter, which is not
present in {{SCMException}} and {{NonRetriableException}}. This results in
unwrap failure and the commands are retried until the retry policy is exhausted
by the client.
Refer: {{org.apache.hadoop.hdds.scm.ha.SCMHAUtils#checkNonRetriableException}}
which is responsible for failing retry.
> SCMExceptions resulting from admin CLI commands are treated as retriable

> In HDDS-10372, I noticed that throwing SCMException instances from the server
> when invalid options are specified (like trying to reconcile an open
> container), the client treats the command as retriable. This means internally
> the client keeps resending the command and the server keeps rejecting it for
> about 30 seconds before it fails and shows the user an error.
> I need to investigate more to see if this error is specific to the
> implementation here or a general problem with the SCM admin protocol. If its
> the later this will be fixed on master instead.
