fsck reports a non-existant DFS path as healthy

I would have expected the following to generate an error message:

-bash-3.00$ bin/hadoop fsck non-existant
Status: HEALTHY
Total size: 0 B
Total blocks: 0
Total dirs: 0
Total files: 0
Over-replicated blocks: 0
Under-replicated blocks: 0
Target replication factor: 3
Real replication factor: 0.0

The filesystem under path 'non-existant' is HEALTHY
