Failed to create Controller auth provider

Error message

Failed to create Controller auth provider

What it means

Mirror of the broker case for the controller: PinotControllerAuthenticationProvider resolves controller session credential getters via reflection and wraps a NoSuchMethodException in a RuntimeException 'Failed to create Controller auth provider'.

Solutions

  1. Rebuild/redeploy the connector so all classes are consistent
  2. Update the reflective lookup names to the current method names or replace reflection with direct calls
  3. Check for recent renames of the controller session property getters
  4. Confirm controller auth type config requires this provider before it is constructed

Example fix

// before
PinotSessionProperties.class.getMethod("getControllerAuthenticationUser", ConnectorSession.class)
// after
session -> PinotSessionProperties.getControllerAuthenticationUser(session)
Defensive patterns

Strategy: try-catch

Validate before calling

// pre-flight reflective check for controller getters
try {
  PinotSessionProperties.class.getMethod("getControllerAuthenticationUser", ConnectorSession.class);
  PinotSessionProperties.class.getMethod("getControllerAuthenticationPassword", ConnectorSession.class);
} catch (NoSuchMethodException e) {
  throw new IllegalStateException("Connector build lacks controller auth session properties", e);
}

Try / catch

try {
  provider = new PinotControllerAuthenticationProvider(pinotConfig);
} catch (RuntimeException e) {
  if (e.getMessage() != null && e.getMessage().contains("Failed to create Controller auth provider")) {
    log.error("Controller auth provider init failed; check build consistency", e);
    provider = PinotAuthenticationProvider.none();
  } else throw e;
}

Prevention

When it happens

Trigger: Constructing the controller auth provider with controller authentication enabled; PinotSessionProperties.getMethod("getControllerAuthenticationUser"/"...Password", ConnectorSession.class) throws NoSuchMethodException because those methods don't exist in the loaded class.

Common situations: Method renames in PinotSessionProperties; mixed jar versions in the deployment; refactor removed controller session properties while auth config still requests user/password mode.
