Yuki Morishita updated CASSANDRA-4572:
--------------------------------------
Attachment: 4572-1.1.txt
When you do File#listFiles on lost+found directory, it returns null. I believe
there are other cases that it returns null, so attached patch just checks null
after File#listFiles is performed.
> lost+found directory in the data dir causes problems again
