$ exiftool '-filename<CreateDate' -d %y%m%d_%H%M%S%%-c.%%le -r /home/ubuntu/house
Warning: No writable tags set from /home/ubuntu/house/120151116163735582.jpg

And when i used 

$ exiftool '-FileName<${CreateDate}_${Exif:Model}.jpg' -d %Y%m%d_%H%M%S-%%2c *  
Warning: [minor] Tag 'CreateDate' not defined - 120151116163715535.jpg

Files with the warning

Warning: No writable tags set from /home/ubuntu/house/120151116163735582.jpg

don't have a tag CreateDate. For this reason, the files can not be renamed.

To illustrate this:

% exiftool '-filename<CreateDate' -d %y%m%d_%H%M%S%%-c.%%le  ~/tmp
Warning: No writable tags set from /home/aboettger/tmp/relax.jpg
    1 directories scanned
    0 image files updated
    1 image files unchanged


% exiftool -CreateDate ~/tmp   
======== /home/aboettger/tmp/relax.jpg
    1 directories scanned
    1 image files read

% exiftool -CreateDate="2011:11:25 12:00:00" ~/tmp
Warning: Duplicate Orientation tag in IFD0 - /home/aboettger/tmp/relax.jpg
    1 directories scanned
    1 image files updated

% exiftool -createdate ~/tmp                      
======== /home/aboettger/tmp/relax.jpg
Create Date                     : 2011:11:25 12:00:00
    1 directories scanned
    1 image files read

% exiftool '-filename<CreateDate' -d %y%m%d_%H%M%S%%-c.%%le  ~/tmp
    1 directories scanned
    1 image files updated

% ls -log ~/tmp 
total 56

As @A.B. said, the files don't have a CreateDate. If these files are from a camera, then the tag you probably want to use instead is DateTimeOriginal, which is set by nearly all cameras.

Try this command:
exiftool -time:all --system:all -s
This will show you all the time tags (but not the file system timestamps) in your file and from there you can figure out what is the best tag to use for your command.
