odd that mapr thinks it owns my cdrom drives? (and unused partition?) maybe either/or decision on system vs mapr isn't enough

Odd that mapr thinks it owns the "disks" that are two cd/dvd rom drives.
I didn't give them to mapr...i.e. mapr thinks it owns:

/dev/sr0   running              OS0K             0      0                  LITE-ON  127.0.0.1  1023        LTR-16102B     
/dev/sr1   running              A091             0      0                  DVDRW    127.0.0.1  1023        IDE_16X

in fact, why is it listing sdb4 also in the list of what it thinks it owns?

I guess maybe there are 3 groups, not two? i.e:
system
mapr
nobody
(sdb4 should be in the nobody group.maybe the cdroms too)


/opt/mapr/conf/disktab is:
