You can't run the command as an non Hadoop admin user account.
You'll need to switch to the hdfs user via sudo su - hdfs
You could also try hdfs dfs -rm -R -skipTrash .Trash/*
I am trying to clear the .Trash folder for an HDFS user with the -immediate option

without the -immediate option, I still see errors
[airflow@airflowetl root]$ hadoop fs -expunge

Does anyone know what could be going on here? Any other debugging advice?
