> Correct me if I'm wrong but if I understand correctly then you guys inject external tokens into the UGI which then you would expect to be maintained by Flink, right? If that's true then: > > * We can take them over in `YarnClusterDescriptor.setTokensFor` > * but don't expect that the responsibility of them will be taken over by the internal framework > > If you need something like that then I would create a new provider/receiver pair for the custom need where the externally generated tokens are externally updated, the new receiver can detect it, triggers a manager cycle and then then the provider updates it. From the Flink error log, the token needed is for checkpoint. It means the token is mainly used for HDFS. That is why I want to use HadoopFSDelegationTokenProvider to refresh it within the internal framework. -- This is an automated message from the Apache Git Service.
