Answer 1

For Hadoop 3.x, if you try to create a file on HDFS when unauthenticated (e.g. user=dr.who) you will get this error.

It is not recommended for systems that need to be secure, however if you'd like to disable file permissions entirely in Hadoop 3 the hdfs-site.xml setting has changed to:

  dfs.permissions.enabled
  false
