hi all， This is a question discussed by the WeChat group.
Q: "The root user I installed previously, but now configure the Hadoop management user to grant all permissions, only reinstalling Dss+linkis, Spark, and the like." A: No need to reinstall. Chown and change the configuration file; Hdfs should also chown Best Regards ------ 康悦 ritakang GitHub：Ritakang0451 E-mail：rita0...@163.com
