Hi @Federico Ceravolo with the latest Ambari version, you can actually automate the dir creation, and include any other changes you need (such as the group moditifcation) by editing a script that is included in Ambari called the post-user creation hook script. You may want to look at it rather than doing it manually for each user via the Ambari Files View or something: https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.0.3/bk_ambari-administration/content/create_user_home_directory.html ...

Also, use FIFO prioritization with it. https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.3.0/org.apache.nifi.processors.standard.EnforceOrder/index.html ...

Hi @John Bowler I've seen this once before when using Windows based folders as the source of the upload. Are you using the Ambari Files view to do the upload?
