[airflow@airflowetl root]$ hadoop fs -expunge -immediate
-expunge: Illegal option -immediate

没有
-immediate选项，我仍然看到错误[airflow@airflowetl root]$ hadoop fs -expunge
20/01/31 11:35:08 WARN hdfs.DFSClient: Cannot get all encrypted trash roots
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): Access denied for user airflow. Superuser privilege is required
有谁知道这里会发生什么？还有其他调试建议吗？
最佳答案
您不能以非Hadoop管理员用户帐户运行命令。
您需要通过sudo su - hdfs切换到hdfs用户
您也可以尝试hdfs dfs -rm -R -skipTrash .Trash/*
