Peter Bacsko updated YARN-10577:
--------------------------------
    Description: 
Currently, users have to use "\-m" or "\-\-convert-placement-rules"  switch to 
convert the placement rules from FS.

Initially, we converted to the old mapping rule format, which has serious 
limitations, so we disabled the automatic conversion.

With the new JSON-based format and placement engine, this conversion should 
happen automatically.
