Sahil Takiar updated HIVE-19785: -------------------------------- Description: There is a race condition that leads to some extraneous exception messages when the timeout task is invoked in {{RpcServer}}. If a timeout is triggered by {{RpcServer#registerClient}} the method will remove the {{clientId}} from {{pendingClients}}. However, if the SASL negotiation is in progress when the timeout task is invoked, then {{SaslServerHandler#update}} will throw an {{IllegalArgumentException}} complaining that it can't find the {{clientId}} in the map of {{pendingClients}}. The timeout still succeeds, but the logging is confusing and multiple exceptions make this difficult to debug. was: There is a race condition that leads to some extraneous exception messages when the timeout task is invoked in {{RpcServer}}.
