---------------------------------------------
{quote}Could you please help me understand the requirement to add
testDigestRPC? Auth is done at the SaslRpcServer layer which we haven't
modified as part of this change.
{quote}
Newly added test covers when AuthMethod is KERBEROS so SASL authentication
will be done through ** KERBEROS*.* As we added *TOKEN* impl (even ZKDTSM was
already exists),SASL auth can be verified through TOKEN with ZKDTSM like
following. I am ok to handle in followup jira
{code:java}
public void testDigest() throws Exception {
TestingServer zkServer = new TestingServer();
zkServer.start();
String connectString = zkServer.getConnectString();
Configuration conf = getSecretConf(connectString);
conf.set(HADOOP_SECURITY_AUTHENTICATION, TOKEN.toString());
RouterSecurityManager rm = new RouterSecurityManager(conf);
SecurityUtil.setSecurityInfoProviders(new DelegationTokensecurityInfo());
final Server server = new RPC.Builder(conf)
.setProtocol(TestSaslProtocol.class).setInstance(new TestSaslImpl())
.setBindAddress(ADDRESS).setPort(0).setNumHandlers(5).setVerbose(true)
.setSecretManager(rm.getSecretManager()).build();
doDigestRpc(server, rm);
}{code}
Apart from the above Patch lgtm. Sorry for delayed review.
