Jason Lowe commented on HADOOP-15284:
-------------------------------------

Looks like this was caused by YARN-7815.  The user's directory that was mounted 
before is always going to be there because the container executor creates the 
underlying container directory, but the user's filecache directory for 
resources with PRIVATE visibility may not be there.

One straightforward fix is to have the container executor ensure the user's 
filecache directory is present when launching Docker containers, but there may 
be cleaner alternatives.
