bq. ambari, handles the creation of necessary HDFS dirs, that works nicely and gives admin
full control of file system layout

Ambari does not handle auto creation of user home directories - I've run it for several years
for several clients at this point and customers still run in to this little bug bear - otherwise
I wouldn't have raised this ticket.

bq. Similarly on linux, user home dirs were not created automatically, that is admin's job.

When you SSH in to Linux systems /etc/skel is copied to instantiate /home/<username>
if it doesn't already exist - this is where I got the idea from, it's been this way for many
years and been a widely useful paradigm for millions of people already.
