By default, Kyuubi leverages the [Hadoop User Impersonation](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/Superusers.html) feature to reduce the keytab management effort on kerberized Hadoop cluster. To simply verify your cluster setup, you can: 1. switch to the OS user that runs the Kyuubi server 2. Kyuubi runs `kinit` in the background, please run `klist` to make sure there is a valid TGT cache for principal "hadoop" 3. submit a Spark application (i.e. SparkPi or something) with an additional option `--proxy-user huchao` I suppose the same error will occur, you should fix it first. -- This is an automated message from the Apache Git Service.
