Description
The work in HDFS-13947 allowed for using ArrayList instead of LinkedList when scanning DataNode local directories, however the FsVolumeSpi implementations were still using (and forcing) LinkedList. I propose changing the FsVolumeSpi signatures to allow for Collection instead of LinkedList. Since I'm looking at the code, I made some small improvements and check-style fixes.
