> Excerpt from HIVE-6837 and related issues:
> 1. SessionManager#openSession:
> {code}
> public SessionHandle openSession(TProtocolVersion protocol, String username,
> String password,
> Map<String, String> sessionConf, boolean withImpersonation, String
> delegationToken)
> throws HiveSQLException {
> HiveSession session;
> if (withImpersonation) {
> HiveSessionImplwithUGI hiveSessionUgi = new
> HiveSessionImplwithUGI(protocol, username, password,
> hiveConf, sessionConf, TSetIpAddressProcessor.getUserIpAddress(),
> delegationToken);
> session = HiveSessionProxy.getProxy(hiveSessionUgi,
> hiveSessionUgi.getSessionUgi());
> hiveSessionUgi.setProxySession(session);
> } else {
> session = new HiveSessionImpl(protocol, username, password, hiveConf,
> sessionConf,
> TSetIpAddressProcessor.getUserIpAddress());
> }
> session.setSessionManager(this);
> session.setOperationManager(operationManager);
> session.open();
> handleToSession.put(session.getSessionHandle(), session);
> try {
> executeSessionHooks(session);
> } catch (Exception e) {
> throw new HiveSQLException("Failed to execute session hooks", e);
> }
> return session.getSessionHandle();
> }
> {code}
> Notice that if withImpersonation is set to true, we're using
> TSetIpAddressProcessor.getUserIpAddress() to get the IP address which is
> wrong for a kerberized setup (should use HiveAuthFactory#getIpAddress).
> 2. Also, in case of a kerberized setup, we're wrapping the transport in a
> doAs (with UGI of the HiveServer2 process) which doesn't make sense to me:
> https://github.com/apache/hive/blob/trunk/shims/common-secure/src/main/java/org/apache/hadoop/hive/thrift/HadoopThriftAuthBridge20S.java#L335.
> 3. The name TSetIpAddressProcessor should be replaced with something more
> meaningful like TPlainSASLProcessor.
> 4. Consolidate thread locals used for username, ipaddress
> 5. Do not directly use TSetIpAddressProcessor; get it via factory like here:
> https://github.com/apache/hive/blob/trunk/service/src/java/org/apache/hive/service/auth/HiveAuthFactory.java#L161
