----------------------------------------
Hi Zheng,
I wonder whether localFileSystem.listStatus will ever throw IOE in the case of
a bad volume? Yours handles the case where the volume doesn't exist at all, but
I can imagine if it's on a broken mount, the listStatus will get an I/O Error
from the underlying filesystem and throw at that point. Do you need to catch
this and handle in the same way as if it were null? Thanks.
