Hello community!
Some blocks from HDFS are corrupted so I tried to move them to /lost+found running "hdfs fsck path/to/dir -move" and the result was:

I don't know the reason of the message "PriviledgedActionException as:hdfs (auth:KERBEROS_SSL) cause:org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]". I run the kinit without errors and I could previously run the "hfds dfsadmin -report" command without any kerberos nor authentication related errors.
Any help will be appreciated.
Thanks!
Guido.
