> As discovered in HADOOP-14441, KMS HA using LoadBalancingKMSClientProvider do
> not share delegation tokens. (a client uses KMS address/port as the key for
> delegation token)
> {code:title=DelegationTokenAuthenticatedURL#openConnection}
> if (!creds.getAllTokens().isEmpty()) {
> InetSocketAddress serviceAddr = new InetSocketAddress(url.getHost(),
> url.getPort());
> Text service = SecurityUtil.buildTokenService(serviceAddr);
> dToken = creds.getToken(service);
> {code}
> But KMS doc states:
> {quote}
> Delegation Tokens
> Similar to HTTP authentication, KMS uses Hadoop Authentication for delegation
> tokens too.
> Under HA, A KMS instance must verify the delegation token given by another
> KMS instance, by checking the shared secret used to sign the delegation
> token. To do this, all KMS instances must be able to retrieve the shared
> secret from ZooKeeper.
> {quote}
> We should either update the KMS documentation, or fix this code to share
> delegation tokens.
